History

Shay Banon 4e0d65453f Add Unassigned meta data Unassigned meta includes additional information as to why a shard is unassigned, this is especially handy when a shard moves to unassigned due to node leaving or shard failure. The additional data is provided as part of the cluster state, and as part of `_cat/shards` API. The additional meta includes the timestamp that the shard has moved to unassigned, allowing us in the future to build functionality such as delay allocation due to node leaving until a copy of the shard is found. closes #11653		2015-06-16 17:01:48 +02:00

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": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
    "methods": ["PUT", "POST"],
    "url": {
      "path": "/{index}",
      "paths": ["/{index}"],
      "parts": {
        "index": {
          "type" : "string",
          "required" : true,
          "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 http://elastic.co
List of HTTP methods for the endpoint
URL specification: path, parts, parameters
Whether body is allowed for the endpoint or not and its description

The methods and url.paths elements list all possible HTTP methods and URLs for the endpoint; it is the responsibility of the developer to use this information for a sensible API on the target platform.

Utilities

The repository contains some utilities in the utils directory:

The thor api:generate:spec will generate the basic JSON specification from Java source code
The thor api:generate:code generates Ruby source code and tests from the specs, and can be extended to generate assets in another programming language

Run bundle install and then thor list in the utils folder.

The full command to generate the api spec is:

thor api:spec:generate --output=myfolder --elasticsearch=/path/to/es
