This PR introduces a new syntactical feature to index expression resolution: The selector.
Selectors, denoted with a :: followed by a recognized suffix will allow users to specify which component of
an index abstraction they would like to operate on within an API call. In this case, an index abstraction is a
concrete index, data stream, or alias; Any abstraction that can be resolved to a set of indices/shards. We
define a component of an index abstraction to be some searchable unit of the index abstraction.
JDK 23 removes the COMPAT locale provider, leaving CLDR as the only option. This commit configures Elasticsearch
to use the CLDR provider when on JDK 23, but still use the existing COMPAT provider when on JDK 22 and below.
This causes some differences in locale behaviour; this also adapts various tests to still work whether run on COMPAT or CLDR.
Handle the "output memory allocator bytes" field if and only if it is present in the model size stats, as reported by the C++ backend.
This PR _must_ be merged prior to the corresponding `ml-cpp` one, to keep CI tests happy.
* Remove `es-test-dir` book-scoped variable
* Remove `plugins-examples-dir` book-scoped variable
* Remove `:dependencies-dir:` and `:xes-repo-dir:` book-scoped variables
- In `index.asciidoc`, two variables (`:dependencies-dir:` and `:xes-repo-dir:`) were removed.
- In `sql/index.asciidoc`, the `:sql-tests:` path was updated to fuller path
- In `esql/index.asciidoc`, the `:esql-tests:` path was updated idem
* Replace `es-repo-dir` with `es-ref-dir`
* Move `:include-xpack: true` to few files that use it, remove from index.asciidoc
In this PR we introduce a new query parameter behind the failure store feature flag. The query param, `faliure_store` allows the multi-syntax supporting APIs to choose the failure store indices as well. If an API should not support failure store, the `allowFailureStore` flag should be `false`.
Recently a user saw spurious delayed data warnings. These turned
out to be due to accidentally setting `summary_count_field` to a
field that was always zero. This meant that every document was
considered delayed.
Certain NLP models such as multilingual-e5-large require a prefix
string to be applied to the input text. For asymmetric tasks such as
information retrieval the prefix can be different when ingesting the
data and when searching it. For example text embedding model can
have a one prefix applied when the model is evaluated as part of an
knn search and a different prefix when ingesting documents.
The _ml/info response now includes two extra fields in its
`limits`:
1. `max_single_ml_node_processors`
2. `total_ml_processors`
These fields are _only_ included if they can be accurately
calculated. If autoscaling is enabled and the ML nodes are
not at their maximum size then these fields _cannot_
currently be accurately calculated. (This could potentially
be improved in the future with additional settings set by
the control plane.)
* Added platform architecture field to TrainedModelMetadata and users of TrainedModelMetadata
* Added TransportVersions guarding for TrainedModelMetadata
* Prevent platform-specific models from being deployed on the wrong architecture
* Added logic to only verify node architectures for models which are platform specific
* Handle null platform architecture
* Added logging for the detection of heterogeneous platform architectures among ML nodes and refactoring to support this
* Added platform architecture field to TrainedModelConfig
* Stop platform-speficic model when rebalance occurs and the cluster has a heterogeneous architecture among ML nodes
* Added logic to TransportPutTrainedModelAction to return a warning response header when the model is paltform-specific and cannot be depoloyed on the cluster at that time due to heterogenous architectures among ML nodes
* Added MlPlatformArchitecturesUtilTests
* Updated Create Trained Models API docs to describe the new platform_architecture optional field.
* Updated/incremented InferenceIndexConstants
* Added special override to make models with linux-x86_64 in the model ID to be platform specific
**Problem:**
For historical reasons, source files for the Elasticsearch Guide's security, watcher, and Logstash API docs are housed in the `x-pack/docs` directory. This can confuse new contributors who expect Elasticsearch Guide docs to be located in `docs/reference`.
**Solution:**
- Move the security, watcher, and Logstash API doc source files to the `docs/reference` directory
- Update doc snippet tests to use security

Add mask_token field to fill_mask of _ml/trained_models.
This change will enable users and Kibana to get the particular mask tokens needed for deployed models by adding a mask_token field to the GET _ml/trained_models API, as an enhancement to support kibana#159577.
Many multi-lingual and newer models use a tokenization scheme similar to
sentence-piece. This PR adds support for one of those tokenization
schemes, XLMRoBERTa.
The main changes are: - Support for xlm_roberta tokenization
configuration - Adding `scores` to the vocabulary document stored,
requiring that scores be the same size as the vocabulary - Adding a new
flat text file to resources that is the spm char normalizer.
