Before #57042 the max_buckets test would consistently pass because the request would consistently fail. In particular, the request would fail on the data node. After #57042 it only fails on the coordinating node. When the max_buckets test is run in a mixed version cluster it consistently fails on *either* the data node or the coordinating node. Except when the coordinating node is missing #43095. In that case if the one data node has #57042 and one does not, *and* the one that doesn't gets the request first, fails it as expected, and then the coordinating node retries the request on the node with #57042. When that happens the request fails mysteriously with "partial shard failures" as the error message but not partial failures reported. This is *exactly* the bug fixed in #43095. This updates the test to be skipped in mixed version clusters without #43095 because they *sometimes* fail the test spuriously. The request fails in those cases, just like we expect, but with a mysterious error message. Closes #57657
Elasticsearch REST API JSON specification
This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.
Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.
Example for the "Create Index" API:
{
"indices.create": {
"documentation":{
"url":"https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html"
},
"stability": "stable",
"url":{
"paths":[
{
"path":"/{index}",
"method":"PUT",
"parts":{
"index":{
"type":"string",
"description":"The name of the index"
}
}
}
]
},
"params": {
"timeout": {
"type" : "time",
"description" : "Explicit operation timeout"
}
},
"body": {
"description" : "The configuration for the index (`settings` and `mappings`)"
}
}
}
The specification contains:
-
The name of the API (
indices.create
), which usually corresponds to the client calls -
Link to the documentation at the http://elastic.co website.
IMPORANT: This should be a live link. Several downstream ES clients use this link to generate their documentation. Using a broken link or linking to yet-to-be-created doc pages can break the Elastic docs build.
-
stability
indicating the state of the API, has to be declared explicitly or YAML tests will failexperimental
highly likely to break in the near future (minor/path), no bwc guarantees. Possibly removed in the future.beta
less likely to break or be removed but still reserve the right to do sostable
No backwards breaking changes in a minor
-
Request URL: HTTP method, path and parts
-
Request parameters
-
Request body specification
NOTE If an API is stable but it response should be treated as an arbitrary map of key values please notate this as followed
{
"api.name": {
"stability" : "stable",
"response": {
"treat_json_as_key_value" : true
}
}
}
Backwards compatibility
The specification follows the same backward compatibility guarantees as Elasticsearch.
- Within a Major, additions only.
- If an item has been documented wrong it should be deprecated instead as removing these might break downstream clients.
- Major version change, may deprecate pieces or simply remove them given enough deprecation time.
Deprecations
The specification schema allows to codify API deprecations, either for an entire API, or for specific parts of the API, such as paths or parameters.
Entire API:
{
"api" : {
"deprecated" : {
"version" : "7.0.0",
"description" : "Reason API is being deprecated"
},
}
}
Specific paths and their parts:
{
"api": {
"url": {
"paths": [
{
"path":"/{index}/{type}/{id}/_create",
"method":"PUT",
"parts":{
"id":{
"type":"string",
"description":"Document ID"
},
"index":{
"type":"string",
"description":"The name of the index"
},
"type":{
"type":"string",
"description":"The type of the document",
"deprecated":true
}
},
"deprecated":{
"version":"7.0.0",
"description":"Specifying types in urls has been deprecated"
}
}
]
}
}
}
Parameters
{
"api": {
"url": {
"params": {
"stored_fields": {
"type": "list",
"description" : "",
"deprecated" : {
"version" : "7.0.0",
"description" : "Reason parameter is being deprecated"
}
}
}
}
}
}
