elasticsearch 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.
