Introduce Histogram grouping function for bucketing/grouping data based
on a given range. Both date and numeric histograms are supported using
the appropriate range declaration (numbers vs intervals).
SELECT HISTOGRAM(number, 50) AS h FROM index GROUP BY h
SELECT HISTOGRAM(date, INTERVAL 1 YEAR) AS h FROM index GROUP BY h
In addition add multiply operator for Intervals
Add docs for intervals and histogram
Fix#36509
Add CURRENT_TIMESTAMP as keyword as well function alongside NOW()
These return the current date/time for the given query, computed when
the statement reaches the server. For completeness, CURRENT_TIMESTAMP
also accepts precision as an optional parameter.
Fix#36534
Add missing `formatTemplate()` for conditional functions which
resulted in incomplete painless script. Moreover the specific
return type of Object in the painless signatures resulted in
casting exceptions when conditional functions are used in the
ORDER BY.
Fixes: #36631
* Enable parallel restore operations
* Add uuid to restore in progress entries to uniquely identify them
* Adjust restore in progress entries to be a map in cluster state
* Added tests for:
* Parallel restore from two different snapshots
* Parallel restore from a single snapshot to different indices to test uuid identifiers are correctly used by `RestoreService` and routing allocator
* Parallel restore with waiting for completion to test transport actions correctly use uuid identifiers
The file structure finder has timeout functionality,
but prior to this change it would not interrupt a
single long-running Grok match attempt.
This commit hooks into the ThreadWatchdog facility
provided by the Grok library to interrupt individual
Grok matches that may be running at the time the
file structure finder timeout expires.
testFailLeaderReplicaShard periodically fails because we concurrently
index to the leader group and close one of its replicas. If a
replication request hits a closing shard, we will fail that shard;
however, failing a shard is supported by the test framework - this makes
the test fail.
Previously, Math.floorMod was used for integers and longs
which has different logic for negative numbers. Also, the
priority of data types check was wrong as if one of the args
is double the evaluation should be with doubles, then for floats,
then longs and finally integers.
Fixes: #36364
This commit adds deprecation warnings when using format specifiers with
joda data formats that will change with java time. It also adds the "8"
prefix which may be used to force the new java time format parsing.
The getters and setters for useDisMax() have been deprecated since at least 6.0,
also there hasn't been any reference to the query parameter in the
documentation. Removing it from the builder and tests and replacing it with
`tieBreaker(1.0f)` where necessary.
* add read_ilm cluster privilege
Although managing ILM policies is best done using the
"manage" cluster privilege, it is useful to have read-only
views.
* adds `read_ilm` cluster privilege for viewing policies and status
* adds Explain API to the `view_index_metadata` index privilege
* add manage_ilm privileges
This commit add support to engine operations for resolving and verifying the sequence number and
primary term of the last modification to a document before performing an operation. This is
infrastructure to move our (optimistic concurrency control)[http://en.wikipedia.org/wiki/Optimistic_concurrency_control] API to use sequence numbers instead of internal versioning.

There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.
Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.
This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
The error message used when attempting to delete a lifecycle policy that
is in use previously only included one index which was using the policy.
It now includes all indices using that policy.
Includes the following:
* Reversion of doc-values changes in LUCENE-8374; we are interested in seeing if this
has an effect on benchmarks for node-stats and index-stats
* More improvements to docvalues updates
`PageCacheRecycler` is the class that creates and holds pages of arrays
for various uses. `BigArrays` is just one user of these pages. This
commit moves the constants that define the page sizes for the recycler
to be on the recycler class.
Changed AutofollowCoordinator makes use of the wait_for_metadata_version
feature in cluster state API and removed hard coded poll interval.
Originates from #35895

An issue was introduced due to the merge of authorization_realms with
the change to use Affix Settings for realms.
The ".type" setting no longer exists as the type is now part of the
setting key.
* Upgrae plugin to latest and expose udp
* Explicit check for windows
* Rename the properties for the port numbers
* Tasks for pre and pos container actions
The auto follow coordinator keeps track of the UUIDs of indices that it has followed. The index UUID strings need to be cleaned up in the case that these indices are removed in the remote cluster.
Relates to #33007
This commit moves the MergedDateFormatter to a package private class and
reworks joda DateFormatter instances to use that instead of a single
DateTimeFormatter with multiple parsers. This will allow the java and
joda multi formats to share the same format parsing method in a
followup.
Redeprecates the `/_xpack/rollup` endpoints in favor of `/_rollup`.
When we cleanup the rollup in a cluster containing 6.x nodes we need to
use `/_xpack/rollup` instead of `/_rollup` because the 6.x nodes don't
know about `/_rollup`. In those cases we must ignore the deprecation
warnings that the 7.0 node will return for the end point.
Closes#36044
* Renamed DAY_OF_WEEK and WEEK_OF_YEAR functions to their ISO version and
added the same functions with different functionality.
* Rewritten the datetime functions documentation to follow the format of the other
functions documentation pages.
This commit modifies BigArrays to take a circuit breaker name and
the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.
Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.
Finally, this commit closes#31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.
1. CCR tests work without any changes
2. `testDanglingIndices` require changes the source code (added TODO).
3. `testIndexDeletionWhenNodeRejoins` because it's using just two
nodes, adding the node to exclusions is needed on restart.
4. `testCorruptTranslogTruncationOfReplica` starts dedicated master
one, because otherwise, the cluster does not form, if nodes are stopped
and one node is started back.
5. `testResolvePath` needs TEST cluster, because all nodes are stopped
at the end of the test and it's not possible to perform checks needed
by SUITE cluster.
6. `SnapshotDisruptionIT`. Without changes, the test fails because Zen2
retries snapshot creation as soon as network partition heals. This
results into the race between creating snapshot and test cleanup logic
(deleting index). Zen1 on the
other hand, also schedules retry, but it takes some time after network
partition heals, so cleanup logic executes latter and test passes. The
check that snapshot is eventually created is added to
the end of the test.
Adds a setting that indicates that an index is done indexing, set by ILM
when the Rollover action completes. This indicates that the Rollover
action should be skipped in any future invocations, as long as the index
is no longer the write index for its alias.
This enables 1) an index with a policy that involves the Rollover action
to have the policy removed and switched to another one without use of
the move-to-step API, and 2) integrations with Beats and CCR.
* This commit is part of our plan to deprecate and ultimately remove the use of _xpack in the REST APIs.
- REST API docs
- HLRC docs and doc tests
- Handle REST actions with deprecation warnings
- Changed endpoints in rest-api-spec and relevant file names
The following updates were made:
- Add a new untyped endpoint `{index}/_explain/{id}`.
- Add deprecation warnings to Rest*Action, plus tests in Rest*ActionTests.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit converts the watcher execution context to use the joda
compat java time objects. It also again removes the joda methods from
the painless whitelist.
For each API, the following updates were made:
- Add deprecation warnings to `Rest*Action`, plus tests in `Rest*ActionTests`.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
* Add non-X-Pack centric rollup endpoints
This commit adds new endpoints for rollup that do not have _xpack in
their path. The purpose for this change is to take these endpoints into
6.x as well so that they can be available in mixed cluster tests too. A
follow-up change will deprecate the use of _xpack in the rollup
endpoints. And finally, in the future, we would remove the _xpack
endpoints.
* Remove import
* Fix typo
Today the `GetDiscoveredNodesAction` waits, possibly indefinitely, to discover
enough nodes to bootstrap the cluster. However it is possible that the cluster
forms before a node has discovered the expected collection of nodes, in which
case the action will wait indefinitely despite the fact that it is no longer
required.
This commit changes the behaviour so that the action fails once a node receives
a cluster state with a nonempty configuration, indicating that the cluster has
been successfully bootstrapped and therefore the `GetDiscoveredNodesAction`
need wait no longer.
Relates #36380 and #36381; reverts 558f4ec278.
Previously, we used a CamelCase to CAMEL_CASE transformation to get the
primary name of a function from its class name which led to some issues
since there are functions that we don't want to be registered this way
(e.g.: IFNULL). To simplify the logic and avoid and "magic"
transformations in the FunctionRegistry a primary name must be provided
explicitely for each function.
The same change is applied for the function resolution (when a function
is used in an SQL statement). There is no CamelCase to CAMEL_CASE
transformation but only upper-casing is applied (fuNcTiOn -> FUNCTION).
This commit creates JodaDateFormatter to replace
FormatDateTimeFormatter. It converts all uses of the old class
to DateFormatter to allow a future change to use JavaDateFormatter
when appropriate.
