+# Persisted Documents
+
+GraphQL _executable documents_ containing at least one operation definition
+and optional fragment defintions can be persisted with a schema.
+
+## Overview
+
+The optional `executables` argument of `@sdl` takes a list of input document files
+that are GraphQL _executable documents_.
+
+```
+  @sdl(
+    files: []
+    executables: [{ document: "operations.graphql", persist: true }]
+  )
+```
+
+When a schema is deployed the _executable documents_ must validate successfully
+against the schema.
+
+By itself this can be used to validate applications' use
+of a GraphQL endpoint remain valid when the schema changes.
+This requires that the application loads GraphQL requests from
+files containing executable documents that are declared in the schema.
+
+In addition any _executable document_ in the schema that is marked with `persist: true`
+is loaded as a _persisted document_.
+
+A client uses a _persisted document_ by specifying its document identifier
+(based upon a SHA256 hash) in a request instead of the content of the _executable document_.
+
+For example instead of this POST body for a request:
+
+```
+{
+  "query": "{__typname}"
+}
+```
+
+a request can use this:
+
+```
+{
+"documentId": "sha256:ecf4edb46db40b5132295c0291d62fb65d6759a9eedfa4d5d612dd5ec54a6b38"
+}
+```
+
+if an _executable document_ was declared in the schema with the matching SHA256 hash.
+
+The request parameters `operationName` and `variables` can be used as required with `documentId`.
+
+## Benefits
+
+Use of persisted documents typically saves network bandwidth as for real application requests
+the hash is smaller than the body of the _executable document_.
+
+In addition query requests can use HTTP GET while maintaining a reasonable sized URL
+that improves caching of URL requests. For example the above request can be a coded as an HTTP GET:
+
+```
+https://london.us-east-a.ibm.stepzen.net/api/customer/graphql?documentId=sha256%3Aecf4edb46db40b5132295c0291d62fb65d6759a9eedfa4d5d612dd5ec54a6b38
+```
+
+## Executable Documents
+
+A good practice is to ensure that a CI/CD process ensures that _executable documents_ declared as
+part of the schema using `@sdl(executables:)` are formatted consistently, using tooling such as `prettier`.
+
+For example the simple _executable document_ shown above `{__typename}` stored in a document file
+and formatted will have contents (including a newline at the end):
+
+```
+{
+  __typename
+}
+```
+
+and thus a document identifier of `sha256:8d8f7365e9e86fa8e3313fcaf2131b801eafe9549de22373089cf27511858b39`.
+
+Clients can obtain the SHA256 hash for a document identifer using any standard mechanism for calculating hashes,
+for example on Linux/Unix systems this command can be used:
+
+```
+shasum -a 256 operations.graphql
+```
+
+When _executable documents_ are persisted using `@sdl(executables:)` the schema calculates the document identifiers automatically.
+
+## Example
+
+This example uses a simple mocked schema with a `Customer` type and a single `Query` field `customer`.
+
+`operations.graphql` contains three GraphQL query operations `Customer`, `CustomerEmail` and `CustomerName`
+each with a different selection against `Query.customer`.
+
+A client can execute them using these request parameters, shown as JavaScript:
+
+```
+{
+  documentId: "sha256:9d50d8e35b5882139e836a126f5d6d5a28cf41c5efd80a6e67f920d284b5f6d0",
+  operationName: "Customer",
+  variables: {
+    id: 1789,
+  },
+}
+```
+
+```
+{
+  documentId: "sha256:9d50d8e35b5882139e836a126f5d6d5a28cf41c5efd80a6e67f920d284b5f6d0",
+  operationName: "CustomerEmail",
+  variables: {
+    id: 2845,
+  },
+}
+```
+
+```
+{
+  documentId: "sha256:9d50d8e35b5882139e836a126f5d6d5a28cf41c5efd80a6e67f920d284b5f6d0",
+  operationName: "CustomerName",
+  variables: {
+    id: 3651,
+  },
+}
+```
+
+For example use `curl` and HTTP `GET` as follows:
+
+```
+curl \
+   --header "Authorization: Apikey $(stepzen whoami --apikey)" \
+   --header "Content-Type: application/json" \
+ 'https://london.us-east-a.ibm.stepzen.net/api/miscellaneous/graphql?documentId=sha256:9d50d8e35b5882139e836a126f5d6d5a28cf41c5efd80a6e67f920d284b5f6d0&operationName=Customer&variables=%7B%22id%22%3A%201789%7D'
+```
