* When an ArrayList RAC creates a child RAC, the start and end offsets need to have the offset of parent's start offset
* Defaults the 2nd window bound to CURRENT ROW when only a single bound is specified
* Removes the windowingStrictValidation warning and throws a hard exception when Order By alongside RANGE clause is not provided with UNBOUNDED or CURRENT ROW as both bounds
Changes:
- No functional change
- Add class `TuningConfigBuilder` to build `IndexTuningConfig`, `CompactionTuningConfig`
- Remove old class `ParallelIndexTestingFactory.TuningConfigBuilder`
- Remove some unused fields and methods
Changes
- No functional change
- Remove unused method `IndexTuningConfig.withPartitionsSpec()`
- Remove unused method `ParallelIndexTuningConfig.withPartitionsSpec()`
- Remove redundant method `CompactTask.emitIngestionModeMetrics()`
- Remove Clock argument from `CompactionTask.createDataSchemasForInterval()` as it was only needed
for one test which was just verifying the value passed by the test itself. The code now uses a `Stopwatch`
instead and test simply verifies that the metric has been emitted.
- Other minor cleanup changes
Better fallback strategy when the broker is unable to materialize the subquery's results as frames for estimating the bytes:
a. We don't touch the subquery sequence till we know that we can materialize the result as frames
Description:
Compaction operations issued by the Coordinator currently run using the native query engine.
As majority of the advancements that we are making in batch ingestion are in MSQ, it is imperative
that we support compaction on MSQ to make Compaction more robust and possibly faster.
For instance, we have seen OOM errors in native compaction that MSQ could have handled by its
auto-calculation of tuning parameters.
This commit enables compaction on MSQ to remove the dependency on native engine.
Main changes:
* `DataSourceCompactionConfig` now has an additional field `engine` that can be one of
`[native, msq]` with `native` being the default.
* if engine is MSQ, `CompactSegments` duty assigns all available compaction task slots to the
launched `CompactionTask` to ensure full capacity is available to MSQ. This is to avoid stalling which
could happen in case a fraction of the tasks were allotted and they eventually fell short of the number
of tasks required by the MSQ engine to run the compaction.
* `ClientCompactionTaskQuery` has a new field `compactionRunner` with just one `engine` field.
* `CompactionTask` now has `CompactionRunner` interface instance with its implementations
`NativeCompactinRunner` and `MSQCompactionRunner` in the `druid-multi-stage-query` extension.
The objectmapper deserializes `ClientCompactionRunnerInfo` in `ClientCompactionTaskQuery` to the
`CompactionRunner` instance that is mapped to the specified type [`native`, `msq`].
* `CompactTask` uses the `CompactionRunner` instance it receives to create the indexing tasks.
* `CompactionTask` to `MSQControllerTask` conversion logic checks whether metrics are present in
the segment schema. If present, the task is created with a native group-by query; if not, the task is
issued with a scan query. The `storeCompactionState` flag is set in the context.
* Each created `MSQControllerTask` is launched in-place and its `TaskStatus` tracked to determine the
final status of the `CompactionTask`. The id of each of these tasks is the same as that of `CompactionTask`
since otherwise, the workers will be unable to determine the controller task's location for communication
(as they haven't been launched via the overlord).
In case of few aggregators for example BloomSqlAggregator, BaseVarianceSqlAggregator etc, the aggName is being updated from a0 to a0:agg, breaching the contract as we would expect the aggName as the name which is passed. This is causing a mismatch while creating a column accessor.
This commit aims to correct those violating sql aggregators.
Add a shuffling based on the resultShuffleSpecFactory after a limit processor depending on the query destination. LimitFrameProcessors currently do not update the partition boosting column, so we also add the boost column to the previous stage, if one is required.
* 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.

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.

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.
