Today if a wildcard, date-math expression or alias expands/resolves
to an index that is search-throttled we still search it. This is likely
not the desired behavior since it can unexpectedly slow down searches
significantly.
This change adds a new indices option that allows `search`, `count`
and `msearch` to ignore throttled indices by default. Users can
force expansion to throttled indices by using `ignore_throttled=true`
on the rest request to expand also to throttled indices.

This moves all Realm settings to an Affix definition.
However, because different realm types define different settings
(potentially conflicting settings) this requires that the realm type
become part of the setting key.
Thus, we now need to define realm settings as:
xpack.security.authc.realms:
file.file1:
order: 0
native.native1:
order: 1
- This is a breaking change to realm config
- This is also a breaking change to custom security realms (SecurityExtension)
This is a forward port of some of the changes made in #8445, specifically the change mentioned in https://github.com/elastic/elasticsearch/pull/34023#issuecomment-433212636.
Currently, in master, the `cluster_stats` collector collects _all_ cluster metadata and indexes it into `.monitoring-es-*`. However, per the discussion linked to above, we decided to collect _only_ the `display_name` cluster metadata setting for now. This PR makes this change.
Add NotEquals node in parser to simplify expressions so that <value1> != <value2> is
no longer translated internally to NOT(<value1> = <value2>)

This adds a new step for checking whether an index is allocated correctly based
on the rules added prior to running the shrink step. It also fixes a bug where
for shrink we are not allowed to have the shards relocating for the shrink step.
This also allows us to simplify AllocationRoutedStep and provide better
feedback in the step info for why either the allocation or the shrink checks
have failed.

We have an example in `reindex`'s docs about copying from many indices
at once. It doesn't work at the moment because we only allow a single
type per index. We didn't notice it in the docs tests because those
tests didn't copy any documents. This change:
1. Adds documents to the docs tests to fully exercise the snippet.
2. Fixes the example by moving all copied documents to the same type.
3. Moves the note about id collisions and expands on it because it is
even more likely than before.
Closes#35150
If the Rollover step would fail due to the next index in sequence
already existing, just skip to the next step instead of going to the
Error step.
This prevents spurious `ResourceAlreadyExistsException`s created by
simultaneous RolloverStep executions from causing ILM to error out
unnecessarily.
This test has a bug that got introduced during the refactoring of #32442. With 2 concurrent term increments,
we can only assert under the operation permit that we are in the correct operation term, not that there is
not already another term bump pending.
Closes#34862
This commit removes the Joda time usage from ILM and the HLRC components of ILM.
It also fixes an issue where using the `?human=true` flag could have caused the
parser not to work. These millisecond fields now follow the standard we use
elsewhere in the code, with additional fields added iff the `human` flag is
specified.
This is a breaking change for ILM, but since ILM has not yet been released, no
compatibility shim is needed.
If the random query string is "now" by accident _and_ we are also not setting
some field names to use explicitely, then we can hit the "mapped_date" field
from default test setup. This correctly leads to the query being was marked as
not cacheable, but we assume and check so later. This change fixes this rare
edge case by making sure we don't hit the "date" field in this rare cases.
Closes#35183
When the engine is asked for historical operations, we check if some of the requested operations
are not yet refreshed and if so we refresh before returning the operations. The refresh check is
based on capturing the local checkpoint before each refresh and comparing that value to the one
requested when `newChangesSnapshot` was called. If the requested range is above the captured
local checkpoint we issue a refresh.
This can currently cause unneeded extra refreshes if the method is called concurrently which may cause unwanted degradation in indexing performance. This is especially relevant for CCR where we always ask for a range below the global checkpoint. That range is guaranteed to be below the local
checkpoint of the shard and one refresh is enough to serve multiple changes requests.
This commit fixes this by introducing a dedicated mutex to make sure the test for whether a refresh
is needed actually wait for concurrents for concurrent refreshes that were caused by another
change refresh.
Note that this is not a big change in semantics as refreshes are serialized by lucene anyway. I also
opted not to keep the synchronization to the changes snapshot request only even if in theory we
can apply it to all refreshes, not matter where they come from.
The suite FollowerFailOverIT is failing because some documents are not
replicated to the follower. Maybe the FollowTask is not working as
expected or the background indexers eat all resources while the follower
cluster is trying to reform after a failover; then CI is not fast enough
to replicate all the indexed docs within 60 seconds (sometimes I see 80k
docs on the leader).
This commit limits the number of documents to be indexed into the leader
index by the background threads so that we can eliminate the latter
case. This change also replaces a docCount assertion with a docIds
assertion so we can have more information if these tests fail again.

This changes the current script.max_size_in_bytes to be dynamic so it can be
set through the cluster settings API. This setting is also applied to inline scripts
in the compile method of ScriptService to prevent excessively long inline
scripts from being compiled. The script length limit is removed from Painless as
this is no longer necessary with the protection in compile.
Currently we create a new netty event loop group for client connections
and all server profiles. Each new group creates new threads for io
processing. This means 2 * num of processors new threads for each group.
A single group should be able to handle all io processing (for the
transports). This also brings the netty module inline with what we do
for nio.
Additionally, this PR renames the worker threads to be the same for
netty and nio.
Previously, testRunStateChangePolicyWithNextStep asserted that the
ClusterState before and after running the steps were equal. The test
only passed due to a race condition: The latch would be triggered by the
step execution, but the cluster state update thread would continue
running before committing the change to the cluster state. This allowed
the test to read the old cluster state and pass the equality check about
99.99% of the time.
The test now waits for the new cluster state to be committed before
checking that it is _not_ equal to the old cluster state.
Currently, we assume that rollback always happens in the test
testRestoreLocalHistoryFromTranslogOnPromotion. However, if the global
checkpoint equals max_seq_no, we won't rollback. This causes the
max_seq_no_of_updates assertion failed because max_seq_no_of_updates
won't be advanced to the global checkpoint. With this commit, we assert
max_seq_no_of_updates in two different paths.
Today we always allocate a full buffer (1024 elements) in a
LuceneChangesSnapshot even though the requesting size is smaller.
With this change, we will use the requesting size as the buffer size if
it's smaller than the default batch size; otherwise uses the default
batch size.
With this commit we differentiate between permanent circuit breaking
exceptions (which require intervention from an operator and should not
be automatically retried) and transient ones (which may heal themselves
eventually and should be retried). Furthermore, the parent circuit
breaker will categorize a circuit breaking exception as either transient
or permanent based on the categorization of memory usage of its child
circuit breakers.
