Adds an important admonition for the built-in `metrics-*-*` and `logs-*-*` index
templates.
Updates several put index template snippets to include a priority.
Uses `my-data-stream` in place of `logs` for data stream examples.
This provides a more intuitive experience for users that copy/paste
their own values into snippets.
This commit fixes the list dangling indices response.
The dangling_indices array is an array of objects
that represent aggregated dangling index information
Changes:
* Adds the `number_of_routing_shards` index setting to index modules docs.
* Updates the split API docs to mention that `number_of_routing_shards`
is a static setting.
Removes the `@timestamp` field mapping from several data stream index
template snippets.
With #59317, the `@timestamp` field defaults to a `date` field data type
for data streams.
This makes the data_stream timestamp field specification optional when
defining a composable template.
When there isn't one specified it will default to `@timestamp`.
The commit makes the following changes:
* The timestamp field of a data stream definition in a composable
index template can only be set to '@timestamp'.
* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and
instead only check that the _timestamp field mapping has been defined on a backing index of a data stream.
* Moved code that injects _timestamp meta field mapping from `MetadataCreateIndexService#applyCreateIndexRequestWithV2Template58956(...)` method
to `MetadataIndexTemplateService#collectMappings(...)` method.
* Fixed a bug (#58956) that cases timestamp field validation to be performed
for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

Small edit highlighting the fact that atomic cluster state change does not guarantee lack of errors for in-flight requests.

This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.
The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.
