8.9.0 Release notes

Client

  • Tested versions of Ruby for 8.9.0: Ruby (MRI) 3.0, 3.1 and 3.2. JRuby 9.3 and JRuby 9.4.
  • Updated product validation. The code for the product validation was refactored in a few ways:
    • Just check header, does not check the version of the server.
    • Warns only once when there's a general server error.
    • Removes the call to '/' (client.info) when doing the first request, checking on the first actual request from the client.
  • Fixes User-Agent code. In the migration to 8.x, the user agent code was extracted into transport, since we're now using that library in other projects. So for the Elasticsearch Client, the user-agent would be reported as the one defined in elastic-transport. This release fixes the issue and brings back the user agent in the format that was being used in 7.x

Helpers

This release introduces two new Helpers in the client:

  • BulkHelper - This helper provides a better developer experience when using the Bulk API. At its simplest, you can send it a collection of hashes in an array, and it will bulk ingest them into {es}.

See Helpers to read more about them.

    • query_ruleset.delete - Deletes a query ruleset.
    • query_ruleset.get - Returns the details about a query ruleset.

8.5.0 Release notes

  • Tested versions of Ruby for 8.5.0: Ruby (MRI) 2.7, 3.0 and 3.1, JRuby 9.3.

Client

With the latest release of elastic-transport - v8.1.0 - this gem now supports Faraday v2. Elasticsearch Ruby has an open dependency on elastic-transport ('elastic-transport', '~> 8'), so when you upgrade your gems, 8.1.0 will be installed. This supports both Faraday v1 and Faraday v2. The main change on dependencies when using Faraday v2 is all adapters, except for the default net_http one, have been moved out of Faraday into separate gems. This means if you're not using the default adapter and you migrate to Faraday v2, you'll need to add the adapter gems to your Gemfile.

These are the gems required for the different adapters with Faraday 2, instead of the libraries on which they were based:

# HTTPCLient
gem 'faraday-httpclient'

# NetHTTPPersistent
gem 'faraday-net_http_persistent'

# Patron
gem 'faraday-patron'

# Typhoeus
gem 'faraday-typhoeus'

Things should work fine if you migrate to Faraday 2 as long as you include the adapter (unless you're using the default one net-http), but worst case scenario, you can always lock the version of Faraday in your project to 1.x: gem 'faraday', '~> 1'

Be aware if migrating to Faraday v2 that it requires at least Ruby 2.6, unlike Faraday v1 which requires 2.4.

Troubleshooting

If you see a message like: :adapter is not registered on Faraday::Adapter (Faraday::Error) Then you probably need to include the adapter library in your gemfile and require it.

Please submit an issue if you encounter any problems.

Client

Elastic Transport

The code for the dependency elasticsearch-transport has been promoted to its own repository and the project and gem have been renamed to elastic-transport. This gem now powers elasticsearch and elastic-enterprise-search. The elasticsearch-transport gem won't be maintained after the last release in the 7.x branch, in favour of elastic-transport.

This will allow us to better address maintainance in both clients and the library itself.

API

The elasticsearch-api library has been generated based on the Elasticsearch 8.0.0 REST specification.

X-Pack Deprecation

X-Pack has been deprecated. The elasticsearch-xpack gem will no longer be maintained after the last release in the 7.x branch. The "X-Pack" integration library codebase was merged into elasticsearch-api. All the functionality is available from elasticsearch-api. The xpack namespace was removed for accessing any APIs other than _xpack (client.xpack.info) and _xpack/usage (client.xpack.usage). But APIs which were previously available through the xpack namespace e.g.: client.xpack.machine_learning are now only available directly: client.machine_learning.

Parameter checking was removed

The code in elasticsearch-api will no longer validate all the parameters sent. It will only validate the required parameters such as those needed to build the path for the request. But other API parameters are going to be validated by Elasticsearch. This provides better forwards and backwards compatibility in the client.

Response object

In previous versions of the client, calling an API endpoint would return the JSON body of the response. With 8.0, we are returning a new Response object Elasticsearch::API::Response. It still behaves like a Hash to maintain backwards compatibility, but adds the status and headers methods from the Elastic::Transport:Transport::Response object:

elastic_ruby(main)> response = client.info
=> #<Elasticsearch::API::Response:0x000055752b0c50a8
 @response=
  #<Elastic::Transport::Transport::Response:0x000055752b0c50f8
   @body=
    {"name"=>"instance",
     "cluster_name"=>"elasticsearch-8-0-0-SNAPSHOT-rest-test",
     "cluster_uuid"=>"oIfRARuYRGuVYybjxQJ87w",

       "minimum_index_compatibility_version"=>"7.0.0"},
     "tagline"=>"You Know, for Search"},
   @headers={"X-elastic-product"=>"Elasticsearch", "content-type"=>"application/json", "content-length"=>"567"},
   @status=200>>
elastic_ruby(main)> response.status
=> 200
elastic_ruby(main)> response.headers
=> {"X-elastic-product"=>"Elasticsearch", "content-type"=>"application/json", "content-length"=>"567"}
elastic_ruby(main)> response['name']

elastic_ruby(main)> response['tagline']
