Global checkpoints are update by the primary and represent the common part of history across shard copies, as know at a given time. The primary is also in charge of periodically broadcast this information to the replicas. See #10708 for more details.

* [TEST] wait for yellow after setup doc tests
We have many places in the doc where we expect and index to be
yellow before we execute a query. Therefore we have to
always wait for yellow after setup.
Relocation of non-primary shards is realized by recovering from the primary shard. Recovery throttling wrongly equates non-primary relocation as recovering a shard from the non-primary relocation source, however.
Closes#18640
give the table description:
```
table.addCell("merges.total", "sibling:pri;alias:mt,mergesTotal;default:false;text-align:right;desc:number of completed merge ops");
table.addCell("pri.merges.total", "default:false;text-align:right;desc:number of completed merge ops");
table.addCell("merges.total_docs", "sibling:pri;alias:mtd,mergesTotalDocs;default:false;text-align:right;desc:docs merged");
table.addCell("pri.merges.total_docs", "default:false;text-align:right;desc:docs merged");
table.addCell("merges.total_size", "sibling:pri;alias:mts,mergesTotalSize;default:false;text-align:right;desc:size merged");
table.addCell("pri.merges.total_size", "default:false;text-align:right;desc:size merged");
```
this is how it should be.
This commit adds a UUID for each snapshot, in addition to the already
existing repository and snapshot name. The addition of UUIDs will enable
more robust handling of the deletion of previous snapshots and lingering
files from partially failed delete operations, on top of being able to
uniquely track each snapshot.

Today, scheduled pings in NettyTransport can start before the transport
is started. Instead, these pings should not be scheduled until after the
transport is started. This commit modifies NettyTransport so that this
is the case.

Today we use `index.routing.allocation.include._id` to filter the allocation
for the shrink target index. That has the sideeffect that the user has to
delete that setting / change it once the primary has been recovered (shrink is done)
This PR adds a dedicated filter that can only be set internally that only filters
allocation for unassigned shards.
Currently we support empty query clauses like the filter in
"constant_score" : { "filter" : { } }
How these clauses are handled depends on the surrounding query.
They later are either ignored, converted to match all or no documents or
passed up further in the query hierarchy. During parsing these claues are
currently represented as EmptyQueryBuilders. When not handled anywhere else,
these special cases need to be checked for on the shard when building the
lucene query.
This is trappy, so this PR changes the parsing of compound queries. Instead
of returning QueryBuilder, the core query parsing method
QueryShardContext#parseInnerQueryBuilder() now return an Optional which can
be empty in the case of empty query clauses. This has the advantage of forcing
callers to deal with this sooner or later. When encountering empty Optionals,
compound query builders now have the choice to ignore them, pass them on or
rewrite to a different query, depending on context.
This commit adds a new aggs-matrix-stats module. The module presents a new class of aggregations called Matrix Aggregations. Matrix aggregations work on multiple fields and produce a matrix as output. The first matrix aggregation provided by the module is matrix_stats aggregation. This aggregation computes the following statistics over a set of fields:
* Covariance
* Correlation
For completeness (and interpretation purposes) the following per-field statistics are also provided:
* sample count
* population mean
* population variance
* population skewness
* population kurtosis
This commit adds a note regarding the difference in configuration for
the Windows service heap size from any other installation of
Elasticsearch.

The setting bootstrap.mlockall is useful on both POSIX-like systems
(POSIX mlockall) and Windows (Win32 VirtualLock). But mlockall is really
a POSIX only thing so the name should not be tied POSIX. This commit
renames the setting to "bootstrap.memory_lock".
Relates #18669
Index deletion requests currently use a custom acknowledgement mechanism that wait for the data nodes to actually delete the data before acknowledging the request to the client. This was initially put into place as a new index with same name could only be created if the old index was wiped as we used the index name as data folder on the data nodes. With PR #16442, we now use the index uuid as folder name which avoids collision between indices that are named the same (deleted and recreated). This allows us to get rid of the custom acknowledgment mechanism altogether and rely on the standard cluster state-based acknowledgment instead.
Closes#18558
If this option is enabled on a processor it silently catches any processor related failure and continues executing the rest of the pipeline.
