New APIs

• ML.UpdateTrainedModelDeployment: Updates certain properties of trained model deployment.

Client

BulkIndexer

Improvements were made to the BulkIndexer memory usage to allow better handling under burst use cases. Thanks to @christos68k and @rockdaboot !

API

• ML.StartTrainedModelDeployment: Description of NumberOfAllocations has been changed in "The total number of allocations this model is assigned across machine learning nodes".
• Security.GetAPIKey: Added WithLimitedBy boolean parameter. Flag to show the limited-by role descriptors of API Keys.
• Security.GetUser: Added WithProfileUID boolean parameter. Flag to retrieve profile uid (if exists) associated to the user.
• Security.GetUserProfile: Changed the description of uid parameter, a comma-separated list of unique identifier for user profiles.
• Security.QueryAPIKeys: Added WithLimitedBy boolean parameter. Flag to show the limited-by role descriptors of API Keys.
• TextStructureFindStructure: Added EcsCompatibility string parameter. Optional parameter to specify the compatibility mode with ECS Grok patterns - may be either 'v1' or 'disabled'.

Typed API

Following multiple feedbacks we decided to remove the builder API for the type tree.

In its place, work has started to further simplify the type tree by removing redundant type aliases. The API also now comes with a helper package named some that allows to call for inline pointers on primitive types.

In addition, a bug was fixed preventing the use of wildcards in index names, and enums are now extensible by default.

The Typed API remains in alpha stage while its development continues.

API

• get, mget and search added force_synthetic_source: 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.
• ML.StartTrainedModelDeployment added cache_size: A byte-size value for configuring the inference cache size. For example, 20mb.
• Snapshot.Get added sort, size, order, from_sort_value, after, offset and slm_policy_filter. More on these in the documentation.

New API

• Security.UpdateAPIKey documentation.

Typed API

As highlighted in the release not for the 8.4.0-alpha.1, this release marks the beginning of the newly arrived TypedClient.

This new API is still in alpha stage and will be release alongside the existing esapi.

A few examples of standard use-cases can be found in the TypedAPI section of the documentation.

This second prerelease of the 8.4.0 updates the API for the client and fixes the serialization for types using additional properties.
