Previously, the segment granularity for tables in the catalog had to be defined in period format, ie `'PT1H'` , `'P1D'`, etc. This disallows a user from defining segment granularity of `'ALL'` for a table in the catalog, which may be a valid use case. This change makes it so that a user may define the segment granularity of a table in the catalog, as any string that results in a valid granularity using either the `Granularity.fromString(str)` method, or `new PeriodGranularity(new Period(value), null, null)`, and that granularity maps to a standard supported granularity, where `GranularityType.isStandard(granularity)` returns true. As a result a user may who wants to assign a catalog table's segment granularity to be hourly, may assign the segment granularity property of the table to be either `PT1H`, or `HOUR`. These are the same formats accepted at query time.
Updated javadoc for `ColumnIndexSupplier.as` to elaborate on the types of indexes callers might want to ask for from the method, as well as help implementors know what kinds of indexes they should implement to participate in filtering
* Defer more expressions in vectorized groupBy.
This patch adds a way for columns to provide GroupByVectorColumnSelectors,
which controls how the groupBy engine operates on them. This mechanism is used
by ExpressionVirtualColumn to provide an ExpressionDeferredGroupByVectorColumnSelector
that uses the inputs of an expression as the grouping key. The actual expression
evaluation is deferred until the grouped ResultRow is created.
A new context parameter "deferExpressionDimensions" allows users to control when
this deferred selector is used. The default is "fixedWidthNonNumeric", which is a
behavioral change from the prior behavior. Users can get the prior behavior by setting
this to "singleString".
* Fix style.
* Add deferExpressionDimensions to SqlExpressionBenchmark.
* Fix style.
* Fix inspections.
* Add more testing.
* Use valueOrDefault.
* Compute exprKeyBytes a bit lighter-weight.
* Add MSQ query context maxNumSegments.
- Default is MAX_INT (unbounded).
- When set and if a time chunk contains more number of segments than set in the
query context, the MSQ task will fail with TooManySegments fault.
* Fixup hashCode().
* Rename and checkpoint.
* Add some insert and replace happy and sad path tests.
* Update error msg.
* Commentary
* Adjust the default to be null (meaning no max bound on number of segments).
Also fix formatter.
* Fix CodeQL warnings and minor cleanup.
* Assert on maxNumSegments tuning config.
* Minor test cleanup.
* Use null default for the MultiStageQueryContext as well
* Review feedback
* Review feedback
* Move logic to common function getPartitionsByBucket shared by INSERT and REPLACE.
* Rename to validateNumSegmentsPerBucketOrThrow() for consistency.
* Add segmentGranularity to error message.
MSQ cannot process null bytes in string fields, and the current workaround is to remove them using the REPLACE function. 'removeNullBytes' context parameter has been added which sanitizes the input string fields by removing these null bytes.
Changes:
- Rename `UsedSegmentChecker` to `PublishedSegmentsRetriever`
- Remove deprecated single `Interval` argument from `RetrieveUsedSegmentsAction`
as it is now unused and has been deprecated since #1988
- Return `Set` of segments instead of a `Collection` from `IndexerMetadataStorageCoordinator.retrieveUsedSegments()`

* Support ListBasedInputRow in Kafka ingestion with header
* Fix up buildBlendedEventMap
* Add new test for KafkaInputFormat with csv value and headers
* Do not use forbidden APIs
* Move utility method to TestUtils
index_realtime tasks were removed from the documentation in #13107. Even
at that time, they weren't really documented per se— just mentioned. They
existed solely to support Tranquility, which is an obsolete ingestion
method that predates migration of Druid to ASF and is no longer being
maintained. Tranquility docs were also de-linked from the sidebars and
the other doc pages in #11134. Only a stub remains, so people with
links to the page can see that it's no longer recommended.
index_realtime_appenderator tasks existed in the code base, but were
never documented, nor as far as I am aware were they used for any purpose.
This patch removes both task types completely, as well as removes all
supporting code that was otherwise unused. It also updates the stub
doc for Tranquility to be firmer that it is not compatible. (Previously,
the stub doc said it wasn't recommended, and pointed out that it is
built against an ancient 0.9.2 version of Druid.)
ITUnionQueryTest has been migrated to the new integration tests framework and updated to use Kafka ingestion.

* Initial support for bootstrap segments.
- Adds a new API in the coordinator.
- All processes that have storage locations configured (including tasks)
talk to the coordinator if they can, and fetch bootstrap segments from it.
- Then load the segments onto the segment cache as part of startup.
- This addresses the segment bootstrapping logic required by processes before
they can start serving queries or ingesting.
This patch also lays the foundation to speed up upgrades.
* Fail open by default if there are any errors talking to the coordinator.
* Add test for failure scenario and cleanup logs.
* Cleanup and add debug log
* Assert the events so we know the list exactly.
* Revert RunRules test.
The rules aren't evaluated if there are no clusters.
* Revert RunRulesTest too.
* Remove debug info.
* Make the API POST and update log.
* Fix up UTs.
* Throw 503 from MetadataResource; clean up exception handling and DruidException.
* Remove unused logger, add verification of metrics and docs.
* Update error message
* Update server/src/main/java/org/apache/druid/server/coordination/SegmentLoadDropHandler.java

Changes:
- Add new task action `RetrieveSegmentsByIdAction`
- Use new task action to retrieve segments irrespective of their visibility
- During rolling upgrades, this task action would fail as Overlord would be on old version
- If new action fails, fall back to just fetching used segments as before
This PR fixes a few bugs with MSQ export. The main change is calling SqlResults#coerce before writing the column. This allows sketches and json to be correctly deserialized. The format of the exported complex columns are similar to those produced by Async MSQ queries with CSV format.
Notes:
Fix printing of complex columns during export. Sketches and JSON are now correctly formatted during export.
Fix an NPE if the writer has not been initialized. Empty export queries will create an empty file at the location.
Fix a bug with counters for MSQ export, where rows were reported for only the first partition.
As part of #16481, we have started uploading the chunks in parallel.
That means that it's not necessary for the part that finished uploading last
to be less than or equal to the chunkSize (as the final part could've been uploaded earlier).
This made a test in RetryableS3OutputStreamTest flaky where we were
asserting that the final part should be smaller than chunk size.
This commit fixes the test, and also adds another test where the file size
is such that all chunk sizes would be of equal size.
* Fix build
* Push tasklogs alongwith service logs
* temp changes to run standard its without unit test results
* test
* minor change
* test
* test
* Update datasource name for ITSystemTableBatchIndexTaskTest
* Publish task logs
* Revert other changes
* update standard-it yaml
* Turn invalid periods into user-facing exception providing more context.
The current exception is targeting the ADMIN persona. Catch that and turn
it into a USER persona instead. Also, provide more context in the error
message.
* Review comment: pass the wrapping expression and stringify.
* Update processing/src/main/java/org/apache/druid/query/expression/ExprUtils.java

Adds versions of
DruidException.defensive(String, Object...)
InvalidInput.exception(String, Object...)
InvalidInput.exception(Throwable, String, Object...)
the versions add a boolean as the first arg and only create and throw
an exception if it's false. It can be used similar to
Preconditions.checkState/checkArgument
