They enable correlation with traces and logs. + +**Descriptive Attributes** (can change over time): + +- `host.name` - Hostname of the service (can change during migration) +- `cloud.region` - Cloud provider region (can change during migration) +- `deployment.environment` - Deployment environment +- `k8s.pod.name` - Kubernetes pod name (changes on pod restart) + +These attributes describe the current state of the resource and may change over time as infrastructure evolves (e.g., during migrations, scaling, restarts). + +### Entity Refs + +The demo demonstrates OTel entity_refs which structure resources into typed entities: + +```json +{ + "resource": { + "attributes": [...], + "entityRefs": [ + { + "type": "service", + "idKeys": ["service.name", "service.namespace", "service.instance.id"], + "descriptionKeys": ["deployment.environment"] + }, + { + "type": "host", + "idKeys": ["host.name"], + "descriptionKeys": ["cloud.region"] + } + ] + } +} +``` + +### Architecture + +``` +OTLP Metrics TSDB Head Parquet Block +┌─────────────────┐ ┌────────────┐ ┌────────────┐ +│ ResourceMetrics │ ──────► │ In-memory │ ──────► │ series_ │ +│ └─ Resource │ Ingest │ storage │ Compact │ metadata. │ +│ └─ Attrs │ │ │ │ parquet │ +│ └─ Entities│ │ │ │ │ +└─────────────────┘ └────────────┘ └────────────┘ + │ │ + ▼ ▼ + ┌─────────────────────────────────┐ + │ /api/v1/resources │ + │ (combined head + blocks) │ + └─────────────────────────────────┘ + │ + ▼ + ┌─────────────────────────────────┐ + │ info() PromQL function │ + │ (enriches metrics at query time)│ + └─────────────────────────────────┘ +``` + +### API Reference + +Query resource attributes: + +```bash +curl 'http://localhost:8101/prometheus/api/v1/resources?match[]={__name__=~".+"}' +``` + +Query with info() function: + +```bash +curl 'http://localhost:8101/prometheus/api/v1/query?query=info(http_requests_total)&time=1234567890' +``` + +Send OTLP metrics with entity_refs: + +```bash +curl -X POST 'http://localhost:8101/otlp/v1/metrics' \ + -H 'Content-Type: application/json' \ + -d '{ + "resourceMetrics": [{ + "resource": { + "attributes": [...], + "entityRefs": [...] + }, + "scopeMetrics": [...] + }] + }' +``` + +### Use Cases + +- **Trace-to-Metrics Correlation**: Use service.name, service.namespace, and service.instance.id to correlate metrics with distributed traces +- **Resource Discovery**: Query what resources have reported metrics +- **Historical Analysis**: Understand which services were active during time ranges +- **Infrastructure Tracking**: Track changes in descriptive attributes (host migrations, region changes) over time diff --git a/development/mimir-monolithic-mode/scripts/otlp-resource-attrs-demo.sh b/development/mimir-monolithic-mode/scripts/otlp-resource-attrs-demo.sh new file mode 100755 index 00000000000..be94aefdc79 --- /dev/null +++ b/development/mimir-monolithic-mode/scripts/otlp-resource-attrs-demo.sh @@ -0,0 +1,686 @@ +#!/bin/bash +# SPDX-License-Identifier: AGPL-3.0-only + +# OTLP Resource & Scope Attributes Persistence Demo for Grafana Mimir +# +# This demo showcases how Mimir persists OTel resource attributes and scope +# (instrumentation library) attributes from OTLP metrics, and makes resource +# attributes queryable via the /api/v1/resources endpoint and info() function. +# +# This is a faithful port of the Prometheus demo at: +# documentation/examples/otlp-resource-attributes/main.go +# +# Prerequisites: +# - curl and jq installed +# - Either: Mimir running in monolithic mode (./compose-up.sh) +# - Or: Use --start-stack to automatically start the stack +# +# Usage: +# ./scripts/otlp-resource-attrs-demo.sh [--start-stack] [--stop-stack] +# +# Options: +# --start-stack Start the docker-compose stack before running the demo +# --stop-stack Stop the docker-compose stack after the demo completes +# --help, -h Show this help message + +set -e + +# Script directory for locating compose scripts +SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +COMPOSE_DIR="$(cd "${SCRIPT_DIR}/.." && pwd)" + +# Flags +START_STACK=false +STOP_STACK=false + +show_usage() { + cat </dev/null) || true + if [ "$http_code" = "200" ]; then + echo -e "${service_name} is ready." + return 0 + fi + attempt=$((attempt + 1)) + printf "\r Attempt %d/%d..."

----------------------------------------------------------------------------- +// The unpack* functions below are adaptations of the algorithms +// described in "Decoding billions of integers per second through vectorization" +// from D. Lemire & L. Boytsov, the following changes were made: +// +// - The paper described two methods for decoding integers called "horizontal" +// and "vertical". The "horizontal" version is the one that applies the best +// to the bit packing done in the Parquet delta encoding; however, it also +// differs in some ways, many compression techniques discussed in the paper +// are not implemented in the Parquet format. +// +// - The paper focuses on implementations based on SSE instructions, which +// describes how to use PMULLD to emulate the lack of variable bit shift +// for packed integers. Our version of the bit unpacking algorithms here +// uses AVX2 and can perform variable bit shifts using VPSRLVD, which yields +// better throughput since the instruction latency is a single CPU cycle, +// vs 10 for VPMULLD. +// +// - The reference implementation at https://github.com/lemire/FastPFor/ uses +// specializations for each bit size, resulting in 32 unique functions. +// Our version here are more generic, we provide 3 variations of the +// algorithm for bit widths 1 to 16, 17 to 26, and 27 to 31 (unpacking 32 +// bits values is a simple copy). In that regard, our implementation is +// somewhat an improvement over the reference, since it uses less code and +// less memory to hold the shuffle masks and shift tables. +// +// Technically, each specialization of our functions could be expressed by the +// algorithm used for unpacking values of 27 to 31 bits. However, multiple steps +// of the main loop can be removed for lower bit widths, providing up to ~35% +// better throughput for smaller sizes. Since we expect delta encoding to often +// result in bit packing values to smaller bit widths, the specializations are +// worth the extra complexity. +// +// For more details, see: https://arxiv.org/pdf/1209.2137v5.pdf +// ----------------------------------------------------------------------------- + +// unpackInt32x1to16bitsAVX2 is the implementation of the bit unpacking +// algorithm for inputs of bit width 1 to 16. +// +// In this version of the algorithm, we can perform a single memory load in each +// loop iteration since we know that 8 values will fit in a single XMM register. +// +// func unpackInt32x1to16bitsAVX2(dst []int32, src []byte, bitWidth uint) +TEXT ·unpackInt32x1to16bitsAVX2(SB), NOSPLIT, $56-56 + NO_LOCAL_POINTERS + MOVQ dst_base+0(FP), AX + MOVQ dst_len+8(FP), DX + MOVQ src_base+24(FP), BX + MOVQ bitWidth+48(FP), CX + + CMPQ DX, $8 + JB tail + + MOVQ DX, DI + SHRQ $3, DI + SHLQ $3, DI + XORQ SI, SI + + MOVQ $1, R8 + SHLQ CX, R8 + DECQ R8 + MOVQ R8, X0 + VPBROADCASTD X0, X0 // bitMask = (1 << bitWidth) - 1 + + MOVQ CX, R9 + DECQ R9 + SHLQ $5, R9 // 32 * (bitWidth - 1) + + MOVQ CX, R10 + DECQ R10 + SHLQ $5, R10 + ANDQ $0xFF, R10 // (32 * (bitWidth - 1)) % 256 + + LEAQ ·shuffleInt32x1to16bits(SB), R11 + VMOVDQA (R11)(R9*1), X1 + VMOVDQA 16(R11)(R9*1), X2 + + LEAQ ·shiftRightInt32(SB), R12 + VMOVDQA (R12)(R10*1), X3 + VMOVDQA 16(R12)(R10*1), X4 +loop: + VMOVDQU (BX), X7 + + VPSHUFB X1, X7, X5 + VPSHUFB X2, X7, X6 + + VPSRLVD X3, X5, X5 + VPSRLVD X4, X6, X6 + + VPAND X0, X5, X5 + VPAND X0, X6, X6 + + VMOVDQU X5, (AX)(SI*4) + VMOVDQU X6, 16(AX)(SI*4) + + ADDQ CX, BX + ADDQ $8, SI + CMPQ SI, DI + JNE loop + VZEROUPPER + + CMPQ SI, DX + JE done + LEAQ (AX)(SI*4), AX + SUBQ SI, DX +tail: + MOVQ AX, dst_base-56(SP) + MOVQ DX, dst_len-48(SP) + MOVQ BX, src_base-32(SP) + MOVQ CX, bitWidth-8(SP) + CALL ·unpackInt32Default(SB) +done: + RET + +// unpackInt32x17to26bitsAVX2 is the implementation of the bit unpacking +// algorithm for inputs of bit width 17 to 26. +// +// In this version of the algorithm, we need to 32 bytes at each loop iteration +// because 8 bit-packed values will span across two XMM registers. +// +// func unpackInt32x17to26bitsAVX2(dst []int32, src []byte, bitWidth uint) +TEXT ·unpackInt32x17to26bitsAVX2(SB), NOSPLIT, $56-56 + NO_LOCAL_POINTERS + MOVQ dst_base+0(FP), AX + MOVQ dst_len+8(FP), DX + MOVQ src_base+24(FP), BX + MOVQ bitWidth+48(FP), CX + + CMPQ DX, $8 + JB tail + + MOVQ DX, DI + SHRQ $3, DI + SHLQ $3, DI + XORQ SI, SI + + MOVQ $1, R8 + SHLQ CX, R8 + DECQ R8 + MOVQ R8, X0 + VPBROADCASTD X0, X0 + + MOVQ CX, R9 + SUBQ $17, R9 + IMULQ $48, R9 // 48 * (bitWidth - 17) + + MOVQ CX, R10 + DECQ R10 + SHLQ $5, R10 + ANDQ $0xFF, R10 // (32 * (bitWidth - 1)) % 256 + + LEAQ ·shuffleInt32x17to26bits(SB), R11 + VMOVDQA (R11)(R9*1), X1 + VMOVDQA 16(R11)(R9*1), X2 + VMOVDQA 32(R11)(R9*1), X3 + + LEAQ ·shiftRightInt32(SB), R12 + VMOVDQA (R12)(R10*1), X4 + VMOVDQA 16(R12)(R10*1), X5 +loop: + VMOVDQU (BX), X6 + VMOVDQU 16(BX), X7 + + VPSHUFB X1, X6, X8 + VPSHUFB X2, X6, X9 + VPSHUFB X3, X7, X10 + VPOR X10, X9, X9 + + VPSRLVD X4, X8, X8 + VPSRLVD X5, X9, X9 + + VPAND X0, X8, X8 + VPAND X0, X9, X9 + + VMOVDQU X8, (AX)(SI*4) + VMOVDQU X9, 16(AX)(SI*4) + + ADDQ CX, BX + ADDQ $8, SI + CMPQ SI, DI + JNE loop + VZEROUPPER + + CMPQ SI, DX + JE done + LEAQ (AX)(SI*4), AX + SUBQ SI, DX +tail: + MOVQ AX, dst_base-56(SP) + MOVQ DX, dst_len-48(SP) + MOVQ BX, src_base-32(SP) + MOVQ CX, bitWidth-8(SP) + CALL ·unpackInt32Default(SB) +done: + RET + +// unpackInt32x27to31bitsAVX2 is the implementation of the bit unpacking +// algorithm for inputs of bit width 27 to 31. +// +// In this version of the algorithm the bit-packed values may span across up to +// 5 bytes.

This works well when you know the schema ahead of +time, but becomes awkward when you need to traverse arbitrary JSON +structures—you end up with `map[string]interface{}` and type assertions +everywhere. + +Packages like `github.com/tidwall/gjson` solve this with path-based queries, +but they re-scan the input for each query. If you're recursively walking a JSON +document, you pay the parsing cost repeatedly. + +`jsonlite` takes a different approach: parse once, traverse many times. The +parser builds a lightweight in-memory index of the entire document in a single +pass. Once parsed, you can navigate the structure freely without re-parsing. + +## Design + +The core insight is that most JSON strings don't contain escape sequences. When +a string like `"hello"` appears in the input, we don't need to copy it—we can +just point directly into the original input buffer. Only strings with escapes +(like `"hello\nworld"`) require allocation for the unescaped result. + +Each JSON value is represented by a `Value` struct containing just two machine +words: a pointer and a packed integer. The integer uses its high bits to store +the value's type (null, boolean, number, string, array, or object) and its low +bits for length information. This bit-packing means the overhead per value is +minimal—16 bytes on 64-bit systems regardless of the value type. + +Arrays and objects are stored as contiguous slices, so iteration is +cache-friendly. Object fields are sorted by key during parsing, enabling binary +search for lookups. + +## Trade-offs + +This design optimizes for read-heavy workloads where you parse once and query +multiple times. If you only need to extract a single value from a large +document, a streaming parser or path-based query might be more appropriate. + +The parser assumes the input remains valid for the lifetime of the parsed +values. If you're parsing from a buffer that gets reused, you'll need to copy +strings out before the buffer changes. + +Numeric values are stored as their original string representation and parsed on +demand when you call `Int()`, `Float()`, etc. This avoids precision loss for +large integers and defers parsing cost until needed, but means repeated numeric +access will re-parse each time. diff --git a/vendor/github.com/parquet-go/jsonlite/convert.go b/vendor/github.com/parquet-go/jsonlite/convert.go new file mode 100644 index 00000000000..31843da80ba --- /dev/null +++ b/vendor/github.com/parquet-go/jsonlite/convert.go @@ -0,0 +1,352 @@ +package jsonlite + +import ( + "encoding/json" + "math" + "strconv" + "time" +) + +// Convertible is the type constraint for the As function, defining all supported +// conversion types. +type Convertible interface { + any | + bool | + int64 | + uint64 | + float64 | + json.Number | + string | + time.Duration | + time.Time | + []any | + []bool | + []int64 | + []uint64 | + []float64 | + []json.Number | + []string | + []time.Duration | + []time.Time | + map[string]any | + map[string]bool | + map[string]int64 | + map[string]uint64 | + map[string]float64 | + map[string]json.Number | + map[string]string | + map[string]time.Duration | + map[string]time.Time +} + +// As converts a JSON value to the specified Go type. +// +// For primitive types (bool, int64, uint64, float64, string, time.Duration, time.Time): +// - Follows the same conversion rules as the corresponding As* function +// - Returns zero value for nil or incompatible types +// +// For json.Number: +// - Returns the number as a json.Number string +// - Returns empty string for non-number values +// +// For slice types ([]T): +// - Converts JSON arrays where each element is converted using the primitive T logic +// - Returns nil for non-array values +// - Returns empty slice for empty arrays +// +// For map types (map[string]T): +// - Converts JSON objects where each value is converted using the primitive T logic +// - Returns nil for non-object values +// - Returns empty map for empty objects +// +// For any types: +// - any: Returns the most natural Go representation (bool, int64, uint64, float64, string, []any, map[string]any) +// - []any: Recursively converts array elements to any +// - map[string]any: Recursively converts object values to any +// +// Examples: +// +// val, _ := Parse(`[1, 2, 3]`) +// nums := As[[]int64](val) // []int64{1, 2, 3} +// +// val, _ := Parse(`{"a": 1, "b": 2}`) +// m := As[map[string]int64](val) // map[string]int64{"a": 1, "b": 2} +func As[T Convertible](v *Value) T { + switch any(*new(T)).(type) { + case bool: + return any(asBool(v)).(T) + case int64: + return any(asInt(v)).(T) + case uint64: + return any(asUint(v)).(T) + case float64: + return any(asFloat(v)).(T) + case json.Number: + return any(asNumber(v)).(T) + case string: + return any(asString(v)).(T) + case time.Duration: + return any(asDuration(v)).(T) + case time.Time: + return any(asTime(v)).(T) + case []any: + return any(asSlice(v, asAny)).(T) + case []bool: + return any(asSlice(v, asBool)).(T) + case []int64: + return any(asSlice(v, asInt)).(T) + case []uint64: + return any(asSlice(v, asUint)).(T) + case []float64: + return any(asSlice(v, asFloat)).(T) + case []json.Number: + return any(asSlice(v, asNumber)).(T) + case []string: + return any(asSlice(v, asString)).(T) + case []time.Duration: + return any(asSlice(v, asDuration)).(T) + case []time.Time: + return any(asSlice(v, asTime)).(T) + case map[string]any: + return any(asMap(v, asAny)).(T) + case map[string]bool: + return any(asMap(v, asBool)).(T) + case map[string]int64: + return any(asMap(v, asInt)).(T) + case map[string]uint64: + return any(asMap(v, asUint)).(T) + case map[string]float64: + return any(asMap(v, asFloat)).(T) + case map[string]json.Number: + return any(asMap(v, asNumber)).(T) + case map[string]string: + return any(asMap(v, asString)).(T) + case map[string]time.Duration: + return any(asMap(v, asDuration)).(T) + case map[string]time.Time: + return any(asMap(v, asTime)).(T) + default: + // Special handling for any to avoid panic when result is nil + r, _ := asAny(v).(T) + return r + } +} + +// asBool coerces the value to a boolean. +func asBool(v *Value) bool { + if v != nil { + switch v.Kind() { + case True: + return true + case Number: + f, err := strconv.ParseFloat(v.json(), 64) + return err == nil && f != 0 + case String, Object, Array: + return v.Len() > 0 + } + } + return false +} + +// asString coerces the value to a string. +func asString(v *Value) string { + if v != nil && v.Kind() != Null { + return v.String() + } + return "" +} + +// asInt coerces the value to a signed 64-bit integer. +func asInt(v *Value) int64 { + if v != nil { + switch v.Kind() { + case True: + return 1 + case Number: + if i, err := strconv.ParseInt(v.json(), 10, 64);

parquet-go/parquet-go

+

+High-performance Go library to manipulate parquet files, initially developed at +Twilio Segment. +

+ +
+ +## Motivation + +Parquet has been established as a powerful solution to represent columnar data +on persistent storage mediums, achieving levels of compression and query +performance that enable managing data sets at scales that reach the petabytes. +In addition, having intensive data applications sharing a common format creates +opportunities for interoperation in our tool kits, providing greater leverage +and value to engineers maintaining and operating those systems. + +The creation and evolution of large scale data management systems, combined with +realtime expectations come with challenging maintenance and performance +requirements, that existing solutions to use parquet with Go were not addressing. + +The `parquet-go/parquet-go` package was designed and developed to respond to those +challenges, offering high level APIs to read and write parquet files, while +keeping a low compute and memory footprint in order to be used in environments +where data volumes and cost constraints require software to achieve high levels +of efficiency. + +## Specification + +Columnar storage allows Parquet to store data more efficiently than, say, +using JSON or Protobuf. For more information, refer to the [Parquet Format Specification](https://github.com/apache/parquet-format). + +## Installation + +The package is distributed as a standard Go module that programs can take a +dependency on and install with the following command: + +```bash +go get github.com/parquet-go/parquet-go +``` + +Go 1.22 or later is required to use the package. + +### Compatibility Guarantees + +The package is currently released as a pre-v1 version, which gives maintainers +the freedom to break backward compatibility to help improve the APIs as we learn +which initial design decisions would need to be revisited to better support the +use cases that the library solves for. These occurrences are expected to be rare +in frequency and documentation will be produce to guide users on how to adapt +their programs to breaking changes. + +## Usage + +The following sections describe how to use APIs exposed by the library, +highlighting the use cases with code examples to demonstrate how they are used +in practice. + +### Writing Parquet Files: [parquet.GenericWriter[T]](https://pkg.go.dev/github.com/parquet-go/parquet-go#GenericWriter) + +A parquet file is a collection of rows sharing the same schema, arranged in +columns to support faster scan operations on subsets of the data set. + +For simple use cases, the `parquet.WriteFile[T]` function allows the creation +of parquet files on the file system from a slice of Go values representing the +rows to write to the file. + +```go +type RowType struct { FirstName, LastName string } + +if err := parquet.WriteFile("file.parquet", []RowType{ + {FirstName: "Bob"}, + {FirstName: "Alice"}, +}); err != nil { + ... +} +``` + +The `parquet.GenericWriter[T]` type denormalizes rows into columns, then encodes +the columns into a parquet file, generating row groups, column chunks, and pages +based on configurable heuristics. + +```go +type RowType struct { FirstName, LastName string } + +writer := parquet.NewGenericWriter[RowType](output) + +_, err := writer.Write([]RowType{ + ... +}) +if err != nil { + ... +} + +// Closing the writer is necessary to flush buffers and write the file footer. +if err := writer.Close(); err != nil { + ... +} +``` + +Explicit declaration of the parquet schema on a writer is useful when the +application needs to ensure that data written to a file adheres to a predefined +schema, which may differ from the schema derived from the writer's type +parameter. The `parquet.Schema` type is a in-memory representation of the schema +of parquet rows, translated from the type of Go values, and can be used for this +purpose. + +```go +schema := parquet.SchemaOf(new(RowType)) +writer := parquet.NewGenericWriter[any](output, schema) +... +``` + +### Reading Parquet Files: [parquet.GenericReader[T]](https://pkg.go.dev/github.com/parquet-go/parquet-go#GenericReader) + +For simple use cases where the data set fits in memory and the program will +read most rows of the file, the `parquet.ReadFile[T]` function returns a slice +of Go values representing the rows read from the file. + +```go +type RowType struct { FirstName, LastName string } + +rows, err := parquet.ReadFile[RowType]("file.parquet") +if err != nil { + ... +} + +for _, c := range rows { + fmt.Printf("%+v\n", c) +} +``` + +The expected schema of rows can be explicitly declared when the reader is +constructed, which is useful to ensure that the program receives rows matching +an specific format; for example, when dealing with files from remote storage +sources that applications cannot trust to have used an expected schema. + +Configuring the schema of a reader is done by passing a `parquet.Schema` +instance as argument when constructing a reader. When the schema is declared, +conversion rules implemented by the package are applied to ensure that rows +read by the application match the desired format (see **Evolving Parquet Schemas**). + +```go +schema := parquet.SchemaOf(new(RowType)) +reader := parquet.NewReader(file, schema) +... +``` + +### Inspecting Parquet Files: [parquet.File](https://pkg.go.dev/github.com/parquet-go/parquet-go#File) + +Sometimes, lower-level APIs can be useful to leverage the columnar layout of +parquet files. The `parquet.File` type is intended to provide such features to +Go applications, by exposing APIs to iterate over the various parts of a +parquet file. + +```go +f, err := parquet.OpenFile(file, size) +if err != nil { + ... +} + +for _, rowGroup := range f.RowGroups() { + for _, columnChunk := range rowGroup.ColumnChunks() { + ... + } +} +``` + +### Evolving Parquet Schemas: [parquet.Convert](https://pkg.go.dev/github.com/parquet-go/parquet-go#Convert) + +Parquet files embed all the metadata necessary to interpret their content, +including a description of the schema of the tables represented by the rows and +columns they contain. + +Parquet files are also immutable; once written, there is not mechanism for +_updating_ a file. If their contents need to be changed, rows must be read, +modified, and written to a new file. + +Because applications evolve, the schema written to parquet files also tend to +evolve over time. Those requirements creating challenges when applications need +to operate on parquet files with heterogenous schemas: algorithms that expect +new columns to exist may have issues dealing with rows that come from files with +mismatching schema versions. + +To help build applications that can handle evolving schemas, `parquet-go/parquet-go` +implements conversion rules that create views of row groups to translate between +schema versions. + +The `parquet.Convert` function is the low-level routine constructing conversion +rules from a source to a target schema. The function is used to build converted +views of `parquet.RowReader` or `parquet.RowGroup`, for example: + +```go +type RowTypeV1 struct { ID int64; FirstName string } +type RowTypeV2 struct { ID int64; FirstName, LastName string } + +source := parquet.SchemaOf(RowTypeV1{}) +target := parquet.SchemaOf(RowTypeV2{}) + +conversion, err := parquet.Convert(target, source) +if err != nil { + ... +} + +targetRowGroup := parquet.ConvertRowGroup(sourceRowGroup, conversion) +... +``` + +Conversion rules are automatically applied by the `parquet.CopyRows` function +when the reader and writers passed to the function also implement the +`parquet.RowReaderWithSchema` and `parquet.RowWriterWithSchema` interfaces. +The copy determines whether the reader and writer schemas can be converted from +one to the other, and automatically applies the conversion rules to facilitate +the translation between schemas. + +At this time, conversion rules only supports adding or removing columns from +the schemas, there are no type conversions performed, nor ways to rename +columns, etc... More advanced conversion rules may be added in the future. + +### Sorting Row Groups: [parquet.GenericBuffer[T]](https://pkg.go.dev/github.com/parquet-go/parquet-go#Buffer) + +The `parquet.GenericWriter[T]` type is optimized for minimal memory usage, +keeping the order of rows unchanged and flushing pages as soon as they are filled. + +Parquet supports expressing columns by which rows are sorted through the +declaration of _sorting columns_ on row groups. Sorting row groups requires +buffering all rows before ordering and writing them to a parquet file. + +To help with those use cases, the `parquet-go/parquet-go` package exposes the +`parquet.GenericBuffer[T]` type which acts as a buffer of rows and implements +`sort.Interface` to allow applications to sort rows prior to writing them +to a file. + +The columns that rows are ordered by are configured when creating +`parquet.GenericBuffer[T]` instances using the `parquet.SortingColumns` function +to construct row group options configuring the buffer. The type of parquet +columns defines how values are compared, see [Parquet Logical Types](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md) +for details. + +When written to a file, the buffer is materialized into a single row group with +the declared sorting columns. After being written, buffers can be reused by +calling their `Reset` method. + +The following example shows how to use a `parquet.GenericBuffer[T]` to order rows +written to a parquet file: + +```go +type RowType struct { FirstName, LastName string } + +buffer := parquet.NewGenericBuffer[RowType]( + parquet.SortingRowGroupConfig( + parquet.SortingColumns( + parquet.Ascending("LastName"), + parquet.Ascending("FistName"), + ), + ), +) + +buffer.Write([]RowType{ + {FirstName: "Luke", LastName: "Skywalker"}, + {FirstName: "Han", LastName: "Solo"}, + {FirstName: "Anakin", LastName: "Skywalker"}, +}) + +sort.Sort(buffer) + +writer := parquet.NewGenericWriter[RowType](output) +_, err := parquet.CopyRows(writer, buffer.Rows()) +if err != nil { + ... +} +if err := writer.Close(); err != nil { + ... +} +``` + +### Merging Row Groups: [parquet.MergeRowGroups](https://pkg.go.dev/github.com/parquet-go/parquet-go#MergeRowGroups) + +Parquet files are often used as part of the underlying engine for data +processing or storage layers, in which cases merging multiple row groups +into one that contains more rows can be a useful operation to improve query +performance; for example, bloom filters in parquet files are stored for each +row group, the larger the row group, the fewer filters need to be stored and +the more effective they become. + +The `parquet-go/parquet-go` package supports creating merged views of row groups, +where the view contains all the rows of the merged groups, maintaining the order +defined by the sorting columns of the groups. + +There are a few constraints when merging row groups: + +- The sorting columns of all the row groups must be the same, or the merge + operation must be explicitly configured a set of sorting columns which are + a prefix of the sorting columns of all merged row groups. + +- The schemas of row groups must all be equal, or the merge operation must + be explicitly configured with a schema that all row groups can be converted + to, in which case the limitations of schema conversions apply. + +Once a merged view is created, it may be written to a new parquet file or buffer +in order to create a larger row group: + +```go +merge, err := parquet.MergeRowGroups(rowGroups) +if err != nil { + ... +} + +writer := parquet.NewGenericWriter[RowType](output) +_, err := parquet.CopyRows(writer, merge.Rows()) +if err != nil { + ... +} +if err := writer.Close(); err != nil { + ... +} +``` + +### Using Bloom Filters: [parquet.BloomFilter](https://pkg.go.dev/github.com/parquet-go/parquet-go#BloomFilter) + +Parquet files can embed bloom filters to help improve the performance of point +lookups in the files. The format of parquet bloom filters is documented in +the parquet specification: [Parquet Bloom Filter](https://github.com/apache/parquet-format/blob/master/BloomFilter.md) + +By default, no bloom filters are created in parquet files, but applications can +configure the list of columns to create filters for using the `parquet.BloomFilters` +option when instantiating writers; for example: + +```go +type RowType struct { + FirstName string `parquet:"first_name"` + LastName string `parquet:"last_name"` +} + +const filterBitsPerValue = 10 +writer := parquet.NewGenericWriter[RowType](output, + parquet.BloomFilters( + // Configures the write to generate split-block bloom filters for the + // "first_name" and "last_name" columns of the parquet schema of rows + // witten by the application. + parquet.SplitBlockFilter(filterBitsPerValue, "first_name"), + parquet.SplitBlockFilter(filterBitsPerValue, "last_name"), + ), +) +... +``` + +Generating bloom filters requires to know how many values exist in a column +chunk in order to properly size the filter, which requires buffering all the +values written to the column in memory. Because of it, the memory footprint +of `parquet.GenericWriter[T]` increases linearly with the number of columns +that the writer needs to generate filters for. This extra cost is optimized +away when rows are copied from a `parquet.GenericBuffer[T]` to a writer, since +in this case the number of values per column in known since the buffer already +holds all the values in memory. + +When reading parquet files, column chunks expose the generated bloom filters +with the `parquet.ColumnChunk.BloomFilter` method, returning a +`parquet.BloomFilter` instance if a filter was available, or `nil` when there +were no filters. + +Using bloom filters in parquet files is useful when performing point-lookups in +parquet files; searching for column rows matching a given value. Programs can +quickly eliminate column chunks that they know does not contain the value they +search for by checking the filter first, which is often multiple orders of +magnitude faster than scanning the column. + +The following code snippet hilights how filters are typically used: + +```go +var candidateChunks []parquet.ColumnChunk + +for _, rowGroup := range file.RowGroups() { + columnChunk := rowGroup.ColumnChunks()[columnIndex] + bloomFilter := columnChunk.BloomFilter() + + if bloomFilter != nil { + if ok, err := bloomFilter.Check(value); err != nil { + ... + } else if !ok { + // Bloom filters may return false positives, but never return false + // negatives, we know this column chunk does not contain the value. + continue + } + } + + candidateChunks = append(candidateChunks, columnChunk) +} +``` + +## Optimizations + +The following sections describe common optimization techniques supported by the +library. + +### Optimizing Reads + +Lower level APIs used to read parquet files offer more efficient ways to access +column values. Consecutive sequences of values are grouped into pages which are +represented by the `parquet.Page` interface. + +A column chunk may contain multiple pages, each holding a section of the column +values. Applications can retrieve the column values either by reading them into +buffers of `parquet.Value`, or type asserting the pages to read arrays of +primitive Go values. The following example demonstrates how to use both +mechanisms to read column values: + +```go +pages := column.Pages() +defer func() { + checkErr(pages.Close()) +}() + +for { + p, err := pages.ReadPage() + if err != nil { + ... // io.EOF when there are no more pages + } + + switch page := p.Values().(type) { + case parquet.Int32Reader: + values := make([]int32, page.NumValues()) + _, err := page.ReadInt32s(values) + ... + case parquet.Int64Reader: + values := make([]int64, page.NumValues()) + _, err := page.ReadInt64s(values) + ... + default: + values := make([]parquet.Value, page.NumValues()) + _, err := page.ReadValues(values) + ... + } +} +``` + +Reading arrays of typed values is often preferable when performing aggregations +on the values as this model offers a more compact representation of the values +in memory, and pairs well with the use of optimizations like SIMD vectorization. + +### Optimizing Writes + +Applications that deal with columnar storage are sometimes designed to work with +columnar data throughout the abstraction layers; it then becomes possible to +write columns of values directly instead of reconstructing rows from the column +values. The package offers two main mechanisms to satisfy those use cases: + +#### A. Writing Columns of Typed Arrays + +The first solution assumes that the program works with in-memory arrays of typed +values, for example slices of primitive Go types like `[]float32`; this would be +the case if the application is built on top of a framework like +[Apache Arrow](https://pkg.go.dev/github.com/apache/arrow/go/arrow). + +`parquet.GenericBuffer[T]` is an implementation of the `parquet.RowGroup` +interface which maintains in-memory buffers of column values. Rows can be +written by either boxing primitive values into arrays of `parquet.Value`, +or type asserting the columns to a access specialized versions of the write +methods accepting arrays of Go primitive types. + +When using either of these models, the application is responsible for ensuring +that the same number of rows are written to each column or the resulting parquet +file will be malformed. + +The following examples demonstrate how to use these two models to write columns +of Go values: + +```go +type RowType struct { FirstName, LastName string } + +func writeColumns(buffer *parquet.GenericBuffer[RowType], firstNames []string) error { + values := make([]parquet.Value, len(firstNames)) + for i := range firstNames { + values[i] = parquet.ValueOf(firstNames[i]) + } + _, err := buffer.ColumnBuffers()[0].WriteValues(values) + return err +} +``` + +```go +type RowType struct { ID int64; Value float32 } + +func writeColumns(buffer *parquet.GenericBuffer[RowType], ids []int64, values []float32) error { + if len(ids) != len(values) { + return fmt.Errorf("number of ids and values mismatch: ids=%d values=%d", len(ids), len(values)) + } + columns := buffer.ColumnBuffers() + if err := columns[0].(parquet.Int64Writer).WriteInt64s(ids); err != nil { + return err + } + if err := columns[1].(parquet.FloatWriter).WriteFloats(values); err != nil { + return err + } + return nil +} +``` + +The latter is more efficient as it does not require boxing the input into an +intermediary array of `parquet.Value`. However, it may not always be the right +model depending on the situation, sometimes the generic abstraction can be a +more expressive model. + +#### B. Implementing parquet.RowGroup + +Programs that need full control over the construction of row groups can choose +to provide their own implementation of the `parquet.RowGroup` interface, which +includes defining implementations of `parquet.ColumnChunk` and `parquet.Page` +to expose column values of the row group. + +This model can be preferable when the underlying storage or in-memory +representation of the data needs to be optimized further than what can be +achieved by using an intermediary buffering layer with `parquet.GenericBuffer[T]`. + +See [parquet.RowGroup](https://pkg.go.dev/github.com/parquet-go/parquet-go#RowGroup) +for the full interface documentation. + +#### C. Using on-disk page buffers + +When generating parquet files, the writer needs to buffer all pages before it +can create the row group. This may require significant amounts of memory as the +entire file content must be buffered prior to generating it. In some cases, the +files might even be larger than the amount of memory available to the program. + +The `parquet.GenericWriter[T]` can be configured to use disk storage instead as +a scratch buffer when generating files, by configuring a different page buffer +pool using the `parquet.ColumnPageBuffers` option and `parquet.PageBufferPool` +interface. + +The `parquet-go/parquet-go` package provides an implementation of the interface +which uses temporary files to store pages while a file is generated, allowing +programs to use local storage as swap space to hold pages and keep memory +utilization to a minimum. The following example demonstrates how to configure +a parquet writer to use on-disk page buffers: + +```go +type RowType struct { ... } + +writer := parquet.NewGenericWriter[RowType](output, + parquet.ColumnPageBuffers( + parquet.NewFileBufferPool("", "buffers.*"), + ), +) +``` + +When a row group is complete, pages buffered to disk need to be copied back to +the output file. This results in doubling I/O operations and storage space +requirements (the system needs to have enough free disk space to hold two copies +of the file). The resulting write amplification can often be optimized away by +the kernel if the file system supports copy-on-write of disk pages since copies +between `os.File` instances are optimized using `copy_file_range(2)` (on linux). + +See [parquet.PageBufferPool](https://pkg.go.dev/github.com/parquet-go/parquet-go#PageBufferPool) +for the full interface documentation. + +#### D. Parallel Column Writes + +For applications that need to maximize throughput when writing large columnar datasets, the library supports writing columns in parallel. This is especially useful when each column can be prepared independently and written concurrently, leveraging multiple CPU cores. + +You can use Go's goroutines to write to each column's `ColumnWriter` in parallel. Each column's values can be written using `WriteRowValues`, and the column must be closed after writing. It is the application's responsibility to ensure that all columns receive the same number of rows, as mismatched row counts will result in malformed files. + +Example: + +```go +columns = writer.ColumnWriters() +var ( + wg sync.WaitGroup + errs = make([]error, len(columns)) + rowCounts = make([]int, len(columns)) +) +for i, col := range columns { + wg.Add(1) + go func(i int, col parquet.ColumnWriter) { + defer wg.Done() + n, err := col.WriteRowValues(values[i]) // values[i] is []parquet.Value for column i + if err != nil { + errs[i] = err + return + } + rowCounts[i] = n + errs[i] = col.Close() + }(i, col) +} +wg.Wait() +// Check errs and rowCounts for consistency +``` + +This approach can significantly reduce the time required to write wide tables or large datasets, especially on multi-core systems. However, you should ensure proper error handling and synchronization, as shown above. + +## Maintenance + +While initial design and development occurred at Twilio Segment, the project is now maintained by the open source community. We welcome external contributors. +to participate in the form of discussions or code changes. Please review to the +[Contribution](./CONTRIBUTING.md) guidelines as well as the [Code of Conduct](./CODE_OF_CONDUCT.md) +before submitting contributions. + +### Continuous Integration + +The project uses [Github Actions](https://github.com/parquet-go/parquet-go/actions) for CI. + +### Debugging + +The package has debugging capabilities built in which can be turned on using the +`PARQUETGODEBUG` environment variable. The value follows a model similar to +`GODEBUG`, it must be formatted as a comma-separated list of `key=value` pairs. + +The following debug flag are currently supported: + +- `tracebuf=1` turns on tracing of internal buffers, which validates that + reference counters are set to zero when buffers are reclaimed by the garbage + collector. When the package detects that a buffer was leaked, it logs an error + message along with the stack trace captured when the buffer was last used. diff --git a/vendor/github.com/parquet-go/parquet-go/allocator.go b/vendor/github.com/parquet-go/parquet-go/allocator.go new file mode 100644 index 00000000000..0c1c3ae261b --- /dev/null +++ b/vendor/github.com/parquet-go/parquet-go/allocator.go @@ -0,0 +1,64 @@ +package parquet + +import ( + "unsafe" + + "github.com/parquet-go/bitpack/unsafecast" +) + +type allocator struct{ buffer []byte } + +func (a *allocator) makeBytes(n int) []byte { + if free := cap(a.buffer) - len(a.buffer); free < n { + newCap := 2 * cap(a.buffer) + if newCap == 0 { + newCap = 4096 + } + for newCap < n { + newCap *= 2 + } + a.buffer = make([]byte, 0, newCap) + } + + i := len(a.buffer) + j := len(a.buffer) + n + a.buffer = a.buffer[:j] + return a.buffer[i:j:j] +} + +func (a *allocator) copyBytes(v []byte) []byte { + b := a.makeBytes(len(v)) + copy(b, v) + return b +} + +func (a *allocator) copyString(v string) string { + b := a.makeBytes(len(v)) + copy(b, v) + return unsafecast.String(b) +} + +func (a *allocator) reset() { + a.buffer = a.buffer[:0] +} + +// rowAllocator is a memory allocator used to make a copy of rows referencing +// memory buffers that parquet-go does not have ownership of. +// +// This type is used in the implementation of various readers and writers that +// need to capture rows passed to the ReadRows/WriteRows methods.

Padding is therefore +// required in the output buffer to avoid triggering a segfault. +// The encodeInt32AVX2 method adds enough padding when sizing the output buffer +// to account for this requirement. +// +// We leverage the two lanes of YMM registers to work on two sets of 4 values +// (in the sequence of VMOVDQU/VPSHUFD, VPAND, VPSLLQ, VPOR), resulting in having +// two sets of bit-packed values in the lower 64 bits of each YMM lane. +// The upper lane is then permuted into a lower lane to merge the two results, +// which may not be aligned on byte boundaries so we shift the lower and upper +// bits and compose two sets of 128 bits sequences (VPSLLQ, VPSRLQ, VBLENDPD), +// merge them and write the 16 bytes result to the output buffer. +TEXT ·encodeMiniBlockInt32x3to16bitsAVX2(SB), NOSPLIT, $0-24 + MOVQ dst+0(FP), AX + MOVQ src+8(FP), BX + MOVQ bitWidth+16(FP), CX + + VPBROADCASTQ bitWidth+16(FP), Y6 // [1*bitWidth...] + VPSLLQ $1, Y6, Y7 // [2*bitWidth...] + VPADDQ Y6, Y7, Y8 // [3*bitWidth...] + VPSLLQ $2, Y6, Y9 // [4*bitWidth...] + + VPBROADCASTQ sixtyfour<>(SB), Y10 + VPSUBQ Y6, Y10, Y11 // [64-1*bitWidth...] + VPSUBQ Y9, Y10, Y12 // [64-4*bitWidth...] + VPCMPEQQ Y4, Y4, Y4 + VPSRLVQ Y11, Y4, Y4 + + VPXOR Y5, Y5, Y5 + XORQ SI, SI +loop: + VMOVDQU (BX)(SI*4), Y0 + VPSHUFD $0b01010101, Y0, Y1 + VPSHUFD $0b10101010, Y0, Y2 + VPSHUFD $0b11111111, Y0, Y3 + + VPAND Y4, Y0, Y0 + VPAND Y4, Y1, Y1 + VPAND Y4, Y2, Y2 + VPAND Y4, Y3, Y3 + + VPSLLVQ Y6, Y1, Y1 + VPSLLVQ Y7, Y2, Y2 + VPSLLVQ Y8, Y3, Y3 + + VPOR Y1, Y0, Y0 + VPOR Y3, Y2, Y2 + VPOR Y2, Y0, Y0 + + VPERMQ $0b00001010, Y0, Y1 + + VPSLLVQ X9, X1, X2 + VPSRLQ X12, X1, X3 + VBLENDPD $0b10, X3, X2, X1 + VBLENDPD $0b10, X5, X0, X0 + VPOR X1, X0, X0 + + VMOVDQU X0, (AX) + + ADDQ CX, AX + ADDQ $8, SI + CMPQ SI, $miniBlockSize + JNE loop + VZEROUPPER + RET + +GLOBL sixtyfour<>(SB), RODATA|NOPTR, $32 +DATA sixtyfour<>+0(SB)/8, $64 +DATA sixtyfour<>+8(SB)/8, $64 +DATA sixtyfour<>+16(SB)/8, $64 +DATA sixtyfour<>+24(SB)/8, $64 + +// func decodeBlockInt32Default(dst []int32, minDelta, lastValue int32) int32 +TEXT ·decodeBlockInt32Default(SB), NOSPLIT, $0-36 + MOVQ dst_base+0(FP), AX + MOVQ dst_len+8(FP), BX + MOVLQZX minDelta+24(FP), CX + MOVLQZX lastValue+28(FP), DX + XORQ SI, SI + JMP test +loop: + MOVL (AX)(SI*4), DI + ADDL CX, DI + ADDL DI, DX + MOVL DX, (AX)(SI*4) + INCQ SI +test: + CMPQ SI, BX + JNE loop +done: + MOVL DX, ret+32(FP) + RET + +// func decodeBlockInt32AVX2(dst []int32, minDelta, lastValue int32) int32 +TEXT ·decodeBlockInt32AVX2(SB), NOSPLIT, $0-36 + MOVQ dst_base+0(FP), AX + MOVQ dst_len+8(FP), BX + MOVLQZX minDelta+24(FP), CX + MOVLQZX lastValue+28(FP), DX + XORQ SI, SI + + CMPQ BX, $8 + JB test + + MOVQ BX, DI + SHRQ $3, DI + SHLQ $3, DI + + VPXOR X1, X1, X1 + MOVQ CX, X0 + MOVQ DX, X1 + VPBROADCASTD X0, Y0 +loopAVX2: + VMOVDQU (AX)(SI*4), Y2 + VPADDD Y0, Y2, Y2 // Y2[:] += minDelta + VPADDD Y1, Y2, Y2 // Y2[0] += lastValue + + VPSLLDQ $4, Y2, Y3 + VPADDD Y3, Y2, Y2 + + VPSLLDQ $8, Y2, Y3 + VPADDD Y3, Y2, Y2 + + VPSHUFD $0xFF, X2, X1 + VPERM2I128 $1, Y2, Y2, Y3 + VPADDD X1, X3, X3 + + VMOVDQU X2, (AX)(SI*4) + VMOVDQU X3, 16(AX)(SI*4) + VPSRLDQ $12, X3, X1 // lastValue + + ADDQ $8, SI + CMPQ SI, DI + JNE loopAVX2 + VZEROUPPER + MOVQ X1, DX + JMP test +loop: + MOVL (AX)(SI*4), DI + ADDL CX, DI + ADDL DI, DX + MOVL DX, (AX)(SI*4) + INCQ SI +test: + CMPQ SI, BX + JNE loop +done: + MOVL DX, ret+32(FP) + RET + +// ----------------------------------------------------------------------------- +// 64 bits +// ----------------------------------------------------------------------------- + +#define deltaInt64AVX2x4(baseAddr) \ + VMOVDQU baseAddr, Y1 \ // [0,1,2,3] + VPERMQ $0b10010011, Y1, Y2 \ // [3,0,1,2] + VPBLENDD $3, Y0, Y2, Y2 \ // [x,0,1,2] + VPSUBQ Y2, Y1, Y2 \ // [0,1,2,3] -

Example id(2) for a column with field id of 2 +// +// # The date logical type is an int32 value of the number of days since the unix epoch +// +// The timestamp precision can be changed by defining which precision to use as an argument. +// Supported precisions are: nanosecond, millisecond and microsecond. Example: +// +// type Message struct { +// TimestampMicros int64 `parquet:"timestamp_micros,timestamp(microsecond)" +// } +// +// Both the time and timestamp tags accept an optional second parameter +// to set the `isAdjustedToUTC` annotation of the parquet logical type. +// Valid values are "utc" or "local". If not specified, the default value +// for this annotation will be "utc", which will set the `isAdjustedToUTC` annotation +// value to true. Example: +// +// type Message struct { +// TimestampMicrosAdjusted int64 `parquet:"timestamp_micros_adjusted,timestamp(microsecond:utc)" +// TimestampMicrosNotAdjusted int64 `parquet:"timestamp_micros_not_adjusted,timestamp(microsecond:local)" +// } +// +// The decimal tag must be followed by two integer parameters, the first integer +// representing the scale and the second the precision; for example: +// +// type Item struct { +// Cost int64 `parquet:"cost,decimal(0:3)"` +// } +// +// Invalid combination of struct tags and Go types, or repeating options will +// cause the function to panic. +// +// As a special case, if the field tag is "-", the field is omitted from the schema +// and the data will not be written into the parquet file(s). +// Note that a field with name "-" can still be generated using the tag "-,". +// +// The configuration of Parquet maps are done via two tags: +// - The `parquet-key` tag allows to configure the key of a map. +// - The `parquet-value` tag allows users to configure a map's values, for example to declare their native Parquet types. +// +// When configuring a Parquet map, the `parquet` tag will configure the map itself. +// +// For example, the following will set the int64 key of the map to be a timestamp: +// +// type Actions struct { +// Action map[int64]string `parquet:"," parquet-key:",timestamp"` +// } +// +// To configure the element of a list, use the `parquet-element` tag. For example, the following will +// set the id of the element field to 2: +// +// type Item struct { +// Attributes []string `parquet:",id(1),list" parquet-element:",id(2)"` +// } +// +// Note that
