[dependabot[bot]]

Bumps elasticsearch from 7.14.1 to 7.15.2.

Release notes

Sourced from elasticsearch's releases.

7.15.2

Client

• API is compatible with Elasticsearch 7.15.2

Nodes

• Documented additional options the metric parameter of the nodes.info API.

7.15.1

Client

• Fixed a performance regression in JSONSerializer.default() when numpy and pandas weren't installed.
• Changed the DeprecationWarning for the body parameter to be a "removed in a future version" instead of "removed in 8.0" in line with the 8.0 roadmap.

API

Search

• The index parameter of the open_point_in_time API is now required, was optional.

7.15.0

Client

We've recently announced our roadmap for 8.0.0 and have begun issuing deprecation warnings in the 7.x release stream to prepare users for upgrading to 8.0.0 when available.

Added

• Added more precise type hints to many API parameters
• Added explicit parameters to AsyncTransport and AIOHttpConnection
• Added MapboxVectorTileSerializer for handling the application/vnd.mapbox-vector-tile mimetype. Because this mimetype is binary rather than text the raw response bytes are forwarded from the serializer without decoding

Fixed

• Reduced amount of time to import the elasticsearch module by delaying imports of pandas and numpy until later in the JSON serialization stage if necessary

APIs

• Deprecated positional arguments for APIs, instead use keyword arguments exclusively.

Search

• Added the search_mvt experimental API
• Added body field parameters to the search, scroll, and clear_scroll APIs
• Deprecated the body parameter of the search, scroll, and clear_scroll APIs

Documents

• Added body field parameters to the update API
• Added the document parameter to the create and index APIs
