Previously numeric values in the field_stats created by the
find_file_structure endpoint were always output with a
decimal point. This looked unfriendly and unnatural for
fields that clearly store integer values. This change
converts integer values to type Integer before output in
the file structure field stats.
This PR is the first step to use seq_no to optimize indexing operations.
The idea is to track the max seq_no of either update or delete ops on a
primary, and transfer this information to replicas, and replicas use it
to optimize indexing plan for index operations (with assigned seq_no).
The max_seq_no_of_updates on primary is initialized once when a primary
finishes its local recovery or peer recovery in relocation or being
promoted. After that, the max_seq_no_of_updates is only advanced internally
inside an engine when processing update or delete operations.

* Add commented out JVM options for G1GC
These options are available now that we will be supporting G1GC for Java 10 and
above. They are also designed so that the CMS options don't have to be commented
out in order for the G1 options to take effect.
* Update wording
This commit reverts most of #33157 as it introduces another race
condition and breaks a common case of watcher, when the first watch is
added to the system and the index does not exist yet.
This means, that the index will be created, which triggers a reload, but
during this time the put watch operation that triggered this is not yet
indexed, so that both processes finish roughly add the same time and
should not overwrite each other but act complementary.
This commit reverts the logic of cleaning out the ticker engine watches
on start up, as this is done already when the execution is paused -
which also gets paused on the cluster state listener again, as we can be
sure here, that the watches index has not yet been created.
This also adds a new test, that starts a one node cluster and emulates
the case of a non existing watches index and a watch being added, which
should result in proper execution.
Closes#33320
This change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.
* Setting SO_LINGER for open but not connected non-blocking sockets
throws on OSX
* Fixed by only applying setting to connected sockets which will save
the same number of FDs as doing it on open sockets anyway
* closes#33879
Today we don't store the auto-generated timestamp of append-only
operations in Lucene; and assign -1 to every index operations
constructed from LuceneChangesSnapshot. This looks innocent but it
generates duplicate documents on a replica if a retry append-only
arrives first via peer-recovery; then an original append-only arrives
via replication. Since the retry append-only (delivered via recovery)
does not have timestamp, the replica will happily optimizes the original
request while it should not.
This change transmits the max auto-generated timestamp from the primary
to replicas before translog phase in peer recovery. This timestamp will
prevent replicas from optimizing append-only requests if retry
counterparts have been processed.

Currently, assertSeqNos assumes that the cluster is stable at the end of
the test (i.e., no more shard movement). However, this assumption does
not always hold. In these cases, we can stop the assertion instead of
failing a test.
Closes#33704
If a shard was serving as a replica when another shard was promoted to
primary, then its Lucene index was reset to the global checkpoint.
However, if the new primary fails before the primary/replica resync
completes and we are now being promoted, we have to restore the reverted
operations by replaying the translog to avoid losing acknowledged writes.

It's possible for the set "seqNos" to contain only the "unFinishedSeq"
in the testConcurrentReplica test. If this is the case, the call
`randomValueOtherThan` won't make any progress because the predicate
will never be false.
This commit removes this expectation because it's incorrect and it's no
longer needed as we have a dedicated test to verify the contains method.

The job deletion logic was scattered around a few places:
the transport action, the job manager and the deletion task.
Overloading the task with deletion logic also meant extra
dependencies in the core package which should be unnecessary.
This commit consolidates all this logic into the transport action
and replaces the deletion task with a plain one that needs not be
aware of deletion logic.
Drops `Settings` from some of the methods to lookup loggers and
deprecates another logger lookup that takes `Settings` because
`Settings` is no longer required to build a logger.
* ingest: support simulate with verbose for pipeline processor
This change better supports the use of simulate?verbose with the
pipeline processor. Prior to this change any pipeline processors
executed with simulate?verbose would not show all intermediate
processors for the inner pipelines.
This changes also moves the PipelineProcess and TrackingResultProcessor
classes to enable instance checks and to avoid overly public classes.
As well this updates the error message for when cycles are detected
in pipelines calling other pipelines.
The high level Rest clients reindex method currently doesn't pass on the
"requests_per_second" that are optionally set in ReindexRequest through the Rest
layer. This change makes sure the value is added to the request parameters if
set and also includes it for the update-by-query and delete-by-query cases.
* Added TRUNCATE function, modified ROUND to accept two parameters instead of one. Made the second parameter optional for both functions.
* Added documentation for both functions.
Removed rules in the grammar that were superfluous, as they
are already "caught" other rules in the same context.
Also switched to exact ambig detection for debug mode
Fixes: #31885
Today all searches happen on the search threadpool which is the correct
behavior in almost any case. Yet, there are exceptions where for instance
searches searches should be passed through a single-thread
thread-pool to reduce impact on a node. This change adds a index-private setting that allows to mark an index as throttled for searches and forks off all non-stats searcher access to this thread-pool for indices that are marked as `index.search.throttled`
Transient settings override persistent settings, but in fact all of the tests
that run as part of `:server:test` and `:server:integTest` will pass if the
precedence is changed to be the other way round. This change adds a test that
verifies the precedence is as documented.
With this commit we clear the fielddata cache per field as it is
supposed to be. Previously we retrieved the proper field from the cache
but then cleared the entire cache anyway.

This change adds "contains" method to LocalCheckpointTracker.
One of the use cases is to check if a given operation has been processed
in an engine or not by looking up its seq_no in LocalCheckpointTracker.

In cases when mixed secure S3 client credentials and insecure S3 client
credentials were used (that is, those defined on the repository), we
were overriding the credentials from the repository using insecure
settings to all the repositories. This commit fixes this by not mixing
up repositories that use insecure settings with those that use secure
settings.
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
With the upcoming instance bindings, the singular *Binding name isn't descriptive enough
with multiple binding types. This renames the existing *Binding classes to *ClassBinding.
Mechanical change (with some error messages changed from binding to class binding by
hand).
