When dealing with tail queries, data is returned descending for the base
criterion yet the rest of the queries are ascending. This caused a
problem during insertion since while in a page, the data is ASC, between
pages the blocks of data is DESC.
This caused incorrectly sorting inside a SequenceGroup which led to
incorrect results.
Further more in case of limit, since the data in a page is ASC, early
return is not possible neither is desc matching. Thus the page needs to
be consumed first before finding the final results.
A future improvement could be to keep only the top N results dropping
the rest during insertion time.

Precommit is setup to run as a dependency of the check task, but
unfortunately this wiring was only happening when the java plugin (but
not java-base plugin) was applied. This commit moves the wiring to occur
whenever the check task exists, which is with the lifecycle-base plugin.
This cleans up a few rough edged in the `variable_width_histogram`,
mostly found by @wwang500:
1. Setting its tuning parameters in an unexpected order could cause the
request to fail.
2. We checked that the maximum number of buckets was both less than
50000 and MAX_BUCKETS. This drops the 50000.
3. Fixes a divide by 0 that can occur of the `shard_size` is 1.
4. Fixes a divide by 0 that can occur if the `shard_size * 3` overflows
a signed int.
5. Requires `shard_size * 3 / 4` to be at least `buckets`. If it is less
than `buckets` we will very consistently return fewer buckets than
requested. For the most part we expect folks to leave it at the
default. If they change it, we expect it to be much bigger than
`buckets`.
6. Allocate a smaller `mergeMap` in when initially bucketing requests
that don't use the entire `shard_size * 3 / 4`. Its just a waste.
7. Default `shard_size` to `10 * buckets` rather than `100`. It *looks*
like that was our intention the whole time. And it feels like it'd
keep the algorithm humming along more smoothly.
8. Default the `initial_buffer` to `min(10 * shard_size, 50000)` like
we've documented it rather than `5000`. Like the point above, this
feels like the right thing to do to keep the algorithm happy.

There was a bug in the geoshape circuit-breaker check where the
hash values array was being allocated before its new size was
accounted for by the circuit breaker.
Fixes#57847.
Introduce a fix to tests by snapshotting a single index+shard in the snapshot that
we get the status for and verifying consistency instead of equality
for total file counts.

Moves the highlighting docs from the deprecated 'Request Body Search'
chapter to the new subpage of the 'Run a search chapter' section.
No substantive changes were made to the content.
* Adding new `require_alias` option to indexing requests (#58917)
This commit adds the `require_alias` flag to requests that create new documents.
This flag, when `true` prevents the request from automatically creating an index. Instead, the destination of the request MUST be an alias.
When the flag is not set, or `false`, the behavior defaults to the `action.auto_create_index` settings.
This is useful when an alias is required instead of a concrete index.

Currently, when we apply a cluster state change to a shard on a non-master node,
we check to see if the mappings need to be updated by comparing the decompressed
serialized mappings from the update against the serialized version of the shard's
existing mappings. However, we already have a much simpler way of checking this,
by comparing mapping versions on the index metadata of the old and new states.
This commit adds a shortcut to MapperService.updateMappings() that compares
these mapping versions, and ignores the merge if they are equal.
This commit makes DateFieldMapper extend ParametrizedFieldMapper,
declaring its parameters explicitly. As well as changes to DateFieldMapper
itself, there are some changes to dynamic mapping code to ensure that
dynamically detected date formats are passed through to new date mapper
builders.
The ILM policy for the source and shrunk indices run separately (ie. they
are two separate managed indices). This fixes the test which exhibited some
flakiness by allowing some time for the ILM policy for the source index
to finish executing.

- Ideally this should not be required but current runtime classpath
seems to require this. We need to revisit the classpath declarations in detail
to be able to remove this type of (in theory) superflous compile only references

* Fix handling of final pipelines when destination is changed (#59522)
This change fixes final pipelines if destination index is changed during pipeline run:
-final pipelines can't change destination anymore, exception is thrown if they try to
-if request/default pipeline changes destination final pipeline from old index won't be executed
-if request/default pipeline changes destination and new index has final pipeline it will be executed
-default pipeline from new index won't be executed
Additionally TransportBulkAction.resolvePipelines was moved to IngestService as it's needed for resolving pipelines from new index. Tests were moved accordingly.
Closes#57968
After the work to retry transient replication failures, the local and
global checkpoint test metadata can be incremented on a different thread
than the test thread. This appears to introduce an extremely rare
scenario where this data is not visible for later test assertions. This
commit fixes the issue by using synchronized maps.
Only available in the ingest context for use in ingest pipelines.
Digests are computed on the UTF-8 encoding of the String and are
returned as hex strings.
sha1() return hex strings of length 40, sha256() returns length 64

Adds a hard_bounds parameter to explicitly limit the buckets that a histogram
can generate. This is especially useful in case of open ended ranges that can
produce a very large number of buckets.
This adds a number of new optional parameters to Parameter, including:
* custom serialization (to handle analyzers)
* deprecated parameter names
* parameter validation
* allowing default values to be based on the values of other parameters
We preserve the previous serialization format of CompletionFieldMapper,
always emitting most fields, in order to meet mapping checks in mixed
version clusters, where the mapper service will check that mappings have
been correctly parsed and updated by checking their serialized outputs.
Implement DATE_PARSE(<date_str>, <pattern_str>) function
which allows to parse a date string according to the specified
pattern into a date object. The patterns allowed are those of
java.time.format.DateTimeFormatter.
Closes#54962

* [ML] add new `custom` field to trained model processors (#59542)
This commit adds the new configurable field `custom`.
`custom` indicates if the preprocessor was submitted by a user or automatically created by the analytics job.
Eventually, this field will be used in calculating feature importance. When `custom` is true, the feature importance for
the processed fields is calculated. When `false` the current behavior is the same (we calculate the importance for the originating field/feature).
This also adds new required methods to the preprocessor interface. If users are to supply their own preprocessors
in the analytics job configuration, we need to know the input and output field names.
Eclipse was confused by #59583. It can't see a the public inner
interface within the superclass. This time. Usually that is fine, but
the Eclipse gods don't like this particular code, I guess.
The MappedFieldType#updateMeta method was used for testing equality checks, but we
no longer need these after #59212 , so we can remove this method and make meta final.
Trying to queue up snapshot deletes by blocking the delete of the latest
index-N doesn't work here. The first delete will block on the delete operation
but only do so after having already written the updated repository data.
Since that repository data will contain no snapshots, the subsequent deletes for
`*` will just fall through and complete instead of queue up.
=> Fixed by simply waiting on all files on master so that we block before updating
the repository data and get to test the queueing of equivalent operations
