Martijn van Groningen aa548f5148 Remove GET `_aliases` api in favour for GET `_alias` api
Currently there are two get aliases apis that both have the same functionality, but have a different response structure. The reason for having 2 apis is historic.

The GET _alias api was added in 0.90.x and is more efficient since it only sends the needed alias data from the cluster state between the master node and the node that received the request. In the GET _aliases api the complete cluster state is send to the node that received the request and then the right information is filtered out and send back to the client.

The GET _aliases api should be removed in favour for the alias api

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.elasticsearch.org/guide/reference/api/admin-indices-create-index/",
    "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://elasticsearch.org
  • 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
