v7.17.8

• Patch releases back to being detached from Elastic stack releases.
• Tested compatibility with Elasticsearch v7.17 APIs.
• Tested versions of Ruby for 7.17.8: Ruby (MRI) 2.7, 3.0, 3.1, 3.2, JRuby 9.3, JRuby 9.4.
• Bugfix in elasticsearch-transport: Fixes enforcing UTF-8 in Response body, causing an error when the string is frozen, particularly when using webmock: issue #63.

8.5.2

API Bugfix

Fixes security.create_service_token API, uses POST when token name isn't present.
Thanks @carlosdelest for reporting in #1961.

8.5.1

Bugfix

Fixes bug when instantiating client with api_key: When passing in api_key and transport_options that don't include headers to the client, the api_key code would overwrite the arguments passed in for transport_options. This was fixed in this Pull Request.
Thanks svdasein for reporting in #1940.

8.5.0

• 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.

API

New APIs

• machine_learning.clear_trained_model_deployment_cache - Clear the cached results from a trained model deployment (Beta).
• security.bulk_update_api_keys - Updates the attributes of multiple existing API keys.

API Changes

• rollup.rollup renamed to indices.downsample. The method now receives the index to downsample (Required) and instead of rollup_index, use target_index as the index to store downsampled data.

API

New APIs

API Changes

• get - Adds new parameter force_synthetic_source (Boolean) Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
• machine_learning.start_trained_model_deployment - Adds new parameter cache_size (String) A byte-size value for configuring the inference cache size. For example, 20mb.
• mget - Adds new parameter force_synthetic_source (Boolean) Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
• search - Adds new parameter force_synthetic_source (Boolean) Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
• snapshot.get - Adds new parameters:
  • sort (String) Allows setting a sort order for the result. Defaults to start_time (options: start_time, duration, name, repository, index_count, shard_count, failed_shard_count).
  • size (Integer) Maximum number of snapshots to return. Defaults to 0 which means return all that match without limit.
  • order (String) Sort order (options: asc, desc).
  • from_sort_value (String) Value of the current sort column at which to start retrieval.
  • after (String) Offset identifier to start pagination from as returned by the 'next' field in the response body.
  • offset (Integer) Numeric offset to start pagination based on the snapshots matching the request. Defaults to 0.
  • slm_policy_filter (String) Filter snapshots by a comma-separated list of SLM policy names that snapshots belong to. Accepts wildcards. Use the special pattern '_none' to match snapshots without an SLM policy.

8.3.0

• Tested versions of Ruby for 8.3.0: Ruby (MRI) 2.7, 3.0 and 3.1, JRuby 9.3.

API

• Added build hash to auto generated code. The code generator obtains the git hash from the Elasticsearch specification and adds it as a comment in the code. This allows us to track the version for each generated class.
• Updated for compatibility with Elasticsearch 8.3's API.

API Changes

• cluster.delete_voting_config_exclusions, cluster.post_voting_config_exclusions - Add new parameter master_timeout (Time) Timeout for submitting request to master.
• machine_learning.infer_trained_model_deployment is renamed to machine_learning.infer_trained_model. The url /_ml/trained_models/{model_id}/deployment/_infer is deprecated since 8.3, use /_ml/trained_models/{model_id}/_infer instead.
• machine_learning.preview_datafeed - Adds new parameters:
  • start (String) The start time from where the datafeed preview should begin
  • end (String) The end time when the datafeed preview should stop
• machine_learning.start_trained_model_deployment - Adds new parameters:
  • number_of_allocations (Integer) The number of model allocations on each node where the model is deployed.
  • threads_per_allocation (Integer) The number of threads used by each model allocation during inference.
  • queue_capacity (Integer) Controls how many inference requests are allowed in the queue at a time.
• search_mvt - Adds new parameter: with_labels (Boolean) If true, the hits and aggs layers will contain additional point features with suggested label positions for the original features
• snapshot.get - Adds new parameter: index_names (Boolean) Whether to include the name of each index in the snapshot. Defaults to true.

New parameters:

• field_caps
  • filters An optional set of filters: can include +metadata,-metadata,-nested,-multifield,-parent
  • types Only return results for fields that have one of the types in the list

New APIs:

• cat.component_templates - Returns information about existing component_templates templates.

8.0.1

API

• Fixes an issue with the generated API code. When updating the code generator for 8.x, the order of arguments.clone in the generated code was changed. This would make it so that we would modify the parameters passed in before cloning them, which is undesired. Issue: #1727.
