elasticsearch 7.14.0.pre

on Ruby Gems

This is a pre-release, but there are some important changes coming in version 7.14.0 of the client:

Client

This release changes the way in which the transport layer and the client interact. Previously, when using elasticsearch-transport, Elasticsearch::Transport::Client had a convenient wrapper, so it could be used as Elasticsearch::Client. Now, we are decoupling the transport layer from the Elasticsearch client. If you're using the elasticsearch gem, not much will change. It will instantiate a new Elasticsearch::Transport::Client when you instantiate Elasticsearch::Client and the endpoints from elasticsearch-api will be available.

Elasticsearch::Client has an attr_accessor for the transport instance:

> client = Elasticsearch::Client.new
> client.transport.class
=> Elasticsearch::Transport::Client
> client.transport.transport.class
=> Elasticsearch::Transport::Transport::HTTP::Faraday

The interaction with elasticsearch-api remains unchanged. You can use the API endpoints just like before:

> client.info
=> {"name"=>"instance",
 "cluster_name"=>"elasticsearch",
 "cluster_uuid"=>"id",
 "version"=>
  {"number"=>"7.14.0",
  ...
},
 "tagline"=>"You Know, for Search"}

Or perform request directly from the client which will return an Elasticsearch::Transport::Response object:

> client.perform_request('GET', '/')
# This is the same as doing client.transport.perform_request('GET', '/')
=> #<Elasticsearch::Transport::Transport::Response:0x000055c80bf94bc8
 @body=
  {"name"=>"instance",
   "cluster_name"=>"elasticsearch",
   "cluster_uuid"=>"id",
   "version"=>
    {"number"=>"7.14.0-SNAPSHOT",
    ...
    },
   "tagline"=>"You Know, for Search"},
 @headers=
  {"content-type"=>"application/json; charset=UTF-8",
   "content-length"=>"571",
   ...
   },
 @status=200>
