This commit increases the xpack.ml.max_open_jobs from 20 to 512. Additionally, it ignores nodes that cannot provide an accurate view into their native memory.
If a node does not have a view into its native memory, we ignore it for assignment.
This effectively fixes a bug with autoscaling. Autoscaling relies on jobs with adequate memory to assign jobs to nodes. If that is hampered by the xpack.ml.max_open_jobs scaling decisions are hampered.
With the introduction of BKD-based geo shape indexing in #32039, the prefix tree indexing method has
been deprecated. From 8.0.0, it will not be allowed to create new mappings using deprecated parameters.

Previously, the ResetFeatureStateStatus object captured its status in a
String, which meant that if we wanted to know if something succeeded or
failed, we'd have to parse information out of the string. This isn't a
good way of doing things.
I've introduced a SUCCESS/FAILURE enum for status constants, and added a
check for failures in the transport action. We return a 207 if some but not all
reset actions fail, and for every failure, we also return information about the
exception or error that caused it.

We rely on the repository implementation correctly handling the case where a
write is aborted before it completes. This is not guaranteed for third-party
repositories.
This commit adds a rare action during analysis which aborts the write
just before it completes and verifies that the target blob is not found
by any node.
add support for the stats and top metrics aggregation in transform. With this change it became
easier to add more multi value aggregations to transform
Limitations:
- only the 1st element of top_metrics gets consumed by transform[*].
- all values of stats will be mapped to double if mapping deduction is used, including count,
sum, min, max

When doing a rolling restart we recommend disabling shard allocation to
avoid unnecessary recoveries. However, this advise is unnecessary or
even harmful when restarting nodes that do not carry any data like a
pure ML node.
Today the only example of calling the cluster allocation explain API above the
fold is the bare `GET /_cluster/allocation/explain` which kind of works but is
not usually what the user wants. This commit changes the docs so that we open
with an example showing how we usually expect it to be called. This will make
it clearer that you should normally specify exactly for which shard you want an
explanation. It also tidies up a few other wrinkles in these docs.

* Updates a cat test snippet to always return by index name in asc order
* Removes several leading slashes
* Reduces length of several snippet delimiters
Closes https://github.com/elastic/elasticsearch/issues/71683
This adds a new `match_only_text` field, which indexes the same data as a `text`
field that has `index_options: docs` and `norms: false` and uses the `_source`
for positional queries like `match_phrase`. Unlike `text`, this field doesn't
support scoring.
This commit adds support for system data streams and also the first use
of a system data stream with the fleet action results data stream. A
system data stream is one that is used to store system data that users
should not interact with directly. Elasticsearch will manage these data
streams. REST API access is available for external system data streams
so that other stack components can store system data within a system
data stream. System data streams will not use the system index read and
write threadpools.
* [DOCS] Focus retrieving selected fields on fields parameter
* Incorporating changes from reviews
* Adding clarifications from review feedback
* Slight wording revisions.
* Clarify language around format parameter and move text out of callout.
Currently when the fleet global checkpoints API returns immediately if
the index is not ready or shards are not ready. This commit modifies the
API to wait on the index and primary shards active up until the timeout
period.
Related to #71449.
This commit revives the documentation of the "Clear Cache" and
"Shard Stats" APIs of Searchable Snapshots that was removed
in #62217. This is a partial revert of the commit b545c55 with
some light wording changes.
