1.4.0

Overview

This release improves experience for VShard clusters users and Tarantool 3 users. It also introduces schema introspection API.

New features

• Space schema introspection API crud.schema (#380).

Bugfixes

• Return explicit error for *_many call with no tuples/objects (#377).
• crud.readview resource cleanup on garbage collect (#379).
• VShard storage user have not execution rights for internal functions (#366).
• Compatibility with Tarantool 3.0 tuple objects (#387).

Infrastructure

• deps.sh installs the vshard instead of the cartridge by default (#364). You could to specify an environment variable CARTIRDGE_VERSION to install the cartridge and run tests cases with it.
• doc/playground.lua does not work with Tarantool 3 (#371).
• Tests with Tarantool 3 (#364).
• Quickstart section in the README.md focuses on usage with vshard instead of Cartridge (#366).

1.3.0

Overview

This release introduces read view support for select and pairs. A read view is an in-memory snapshot of data on instance that isn't affected by future data modifications. For a sharded cluster, we open a read view on each storage when one is requested from the router. Read views are supported for Tarantool Enterprise since 2.11.

New features

• Read view support for select and pairs (#343).

1.2.0

Overview

This release add two new flags: noreturn to ignore return values excessive transfer and encoding/decoding for insert/replace/etc (performance improvement up to 10% for batch requests) and fetch_latest_metadata to force fetching latest space format metadata right after a live migration (performance overhead may be up to 15%).

New features

• Add noreturn option for operations: insert, insert_object, insert_many, insert_object_many, replace, replace_object, replace_many, insert_object_many, upsert, upsert_object, upsert_many, upsert_object_many, update, delete (#267).

Bugfixes

• Crud DML operations returning stale schema for metadata generation. Now you may use fetch_latest_metadata flag to work with latest schema (#236).

1.1.1

Overview

This release fixes a critical bug that resulted in 100% storage CPU load and fixes a couple of issues related to the development pipeline.

Changes

• Rename DEV environment variable to TARANTOOL_CRUD_ENABLE_INTERNAL_CHECKS (#250).

Bugfixes

• Yield on select/pairs storage tuple lookup (#312).
• Fix loaded functions misleading coverage (#249).

1.1.0

Overview

This release introduces new API to check module version in code, as well as several compatibility bugfixes.

New features

• Add versioning support (PR #342).

Bugfixes

• Fix pre-hotreload cartridge support (older than 2.4.0) (PR #341).
• Fix Tarantool version-dependent features for 3.x (PR #344).

1.0.0

Overview

This release introduces a breaking change with removing a deprecated feature: crud.len(space_id).

This release also introduces a Cartridge clusterwide config to setup crud.cfg.

Breaking changes

You cannot use space id as a space identifier in crud.len anymore. Use space name instead.

New features

• Timeout condition for the validation of master presence in replicaset and for the master connection (#95).
• Cartridge clusterwide configuration for crud.cfg (#332).

Changes

• Forbid using space id in crud.len (#255).

Fixes

• Add validation of the master presence in replicaset and the master connection to the utils.get_space method before receiving the space from the connection (#331).
• Fix fiber cancel on schema reload timeout in call_reload_schema (PR #336).

0.14.1

Overview

This release introduces the support of sequences for insert_object, insert_object_many, replace_object, replace_object_many and impoved error messages for some cases.

Warning: there is no native support for sequences in sharded systems since each replicaset has its own sequence. If sequence field is a part of the sharding key (which is true by default), choosing the bucket id is the sole responsibility of the developer.

New features

• skip_nullability_check_on_flatten option for insert_object, insert_object_many, replace_object, replace_object_many. false by default. By setting the option to true you allow setting null values to non-nullable fields (#328).

Changes

• Rework NonInitialized error message to be more helpful for troubleshooting (#326).

0.14.0

Overview

This release introduces vshard group and non-default vshard routers support.

To use a space from Cartridge vshard group, pass the group name to a vshard_group request option.

local res, err = crud.select('customers',
                             {{'<=', 'age', 35}},
                             {first = 10, vshard_group = 'hot'})

To use a space from non-default vshard router, pass the router object to a request.

local vshard_router = vshard.router.new(name, cfg)
local res, err = crud.select('customers',
                             {{'<=', 'age', 35}},
                             {first = 10, vshard_group = vshard_router})

New features

• vshard group and non-default vshard routers support (#44).

Changes

• Deprecate using space id in crud.len (#255).
