elasticsearch-api 7.16.0 on Ruby Gems

7.16.0

Client

Adds the delay_on_retry parameter, a value in milliseconds to wait between each failed connection, thanks DinoPullerUqido! Pull Request and backport.
Adds CA fingerprinting. You can configure the client to only trust certificates that are signed by a specific CA certificate (CA certificate pinning) by providing a ca_fingerprint option. This will verify that the fingerprint of the CA certificate that has signed the certificate of the server matches the supplied value:

ca_fingerprint = '64F2593F...'
client = Elasticsearch::Client.new(
  host: 'https://elastic:changeme@localhost:9200',
  transport_options: { ssl: { verify: false } },
  ca_fingerprint: ca_fingerprint
)

The verification will be run once per connection.

Fixes compression. When compression is set to true, the client will now gzip the request body properly and use the appropiate headers. Thanks johnnyshields! Pull Request and backport.

API

Updates

Cleaned up some deprecated code.
count - The API is documented as using GET, but it supports both GET and POST on the Elasticsearch side. So it was updated to only use POST when there's a body present, or else use GET. Elasticsearch would still accept a body with GET, but to be more semantically correct in the clients we use POST when there's a body.
delete_index_template was updated to support the ignore_404 parameter to ignore 404 errors when attempting to delete a non-existing template.
ingest.put_pipeline adds new parameter if_version: Required version for optimistic concurrency control for pipeline updates.
ml.put_trained_model: adds new parameter defer_definition_decompression: If set to true and a compressed_definition is provided, the request defers definition decompression and skips relevant validations.
nodes.hot_threads adds new parameter sort: The sort order for 'cpu' type (default: total) (options: cpu, total).
open_point_in_time: keep_alive is now a required parameter.
search_mvt: adds new parameter track_total_hits: Indicate if the number of documents that match the query should be tracked. A number can also be specified, to accurately track the total hit count up to the number.
transform.preview_transform: adds new parameter transform_id. Body is now optional and the API will use GET or POST depending on the presence of a body.
