Adding the ability to limit the pages sizes of select queries.
We piggyback on the same machinery that is used to control the numRowsPerSegment.
This patch introduces a new context parameter rowsPerPage for which the default value is set to 100000 rows.
This patch also optimizes adding the last selectResults stage only when the previous stages have sorted outputs. Currently for each select query with selectDestination=durableStorage, we used to add this extra selectResults stage.

EARLIEST and LATEST operators implicitly reference the __time column for calculation of the aggregate value. Since the reference isn't explicit, Calcite sometimes fails to update the __time column name when there's column renaming --such as in the case of nested queries -- resulting in column not found errors.
This change rewrites these operators to EARLIEST_BY and LATEST_BY during query processing to make the reference explicit to Calcite.
Update jetty dependencies version to 9.4.53.v20231009
Update netty4 dependencies version to 4.1.100.Final to resolve CVE-2023-4586 (Netty-handler does not validate host names by default)
This relies on the work done in #14322 and #15076. It allows the user to set waitTillSegmentsLoad in the query context (if they want, else it defaults to true) and shows the results in the UI :
- introduces a test_X method for every testcase (995 testcases)
- added a resultset parser which reads the expected resultset based on the result schema
- loaded a few more datasets
- added a testcase to ensure that all files have a corresponding testcase
- renamed DecoupledIgnore to NegativeTest
- categorized the failing 268 tests
This patch changes the thread name of the processing pool of the indexers/peons/historicals from query.getType() + "_" + query.getDataSource() + "_" + query.getIntervals() to query.getId()
MSQ uses the string dimension schema for ARRAY<STRING> typed columns, which creates MVDs instead of string arrays as required. Therefore someone trying to ingest columns of type ARRAY<STRING> from an external data source or another data source would get STRING columns in the newly generated segments.
This patch changes the following:
- Use auto dimension schema to ingest the ARRAY<STRING> columns, which will create columns with the desired type.
- Add an undocumented flag ingestStringArraysAsMVDs to preserve the legacy behavior. Legacy behaviour is turned on by default.
- Create MSQArraysInsertTest and refactor some of the tests in MSQInsertTest.
* add a bunch of tests with array typed columns to CalciteArraysQueryTest
* fix a bug with unnest filter pushdown when filtering on unnested array columns
This PR aims to add the capabilities to:
1. Fetch the realtime segment metadata from the coordinator server view,
2. Adds the ability for workers to query indexers, similar to how brokers do the same for native queries.
* Fix IndexerWorkerClient#fetchChannelData when response has data and error.
When a channel data response from a worker includes some data and then
some I/O error, then when the call is retried, we will re-read the set
of data that was read by the previous connection and add it to the
local channel again. This causes the local channel to become corrupted.
The patch fixes this case by skipping data that has already been read.
Instead of passing the constants around in a new parameter; InputAccessor was introduced to take care of transparently handling the constants - this new class started picking up some copy-paste debris around field accesses; and made them a little bit more readble.
The sql standard is not very restrictive regarding this:
If AVG is specified and DT is exact numeric, then the declared type of the result is an implemen-
tation-defined exact numeric type with precision not less than the precision of DT and scale not
less than the scale of DT.
so; using the same type is also ok (without patch);
however the avg of 0 and 1 is 0 right now because of the retention of the integer typ
Postgres,MySql and Oracle and Drill seem to increase precision ; mssql returns 0

I think we should also increase precision as its already calculated more precisely
* Updating plans when using joins with unnest on the left
* Correcting segment map function for hashJoin
* The changes done here are not reflected into MSQ yet so these tests might not run in MSQ
* native tests
* Self joins with unnest data source
* Making this pass
* Addressing comments by adding explanation and new test
* run build and unit test using Java 21
* run static checks with Java 21
* use setup-java for unit tests, since Java 21 is not built-in
* skip maven cache from setup-java
* add comments to explain cache behavior
Add segmentLoadWait as a query context parameter. If this is true, the controller queries the broker and waits till the segments created (if any) have been loaded by the load rules. The controller also provides this information in the live reports and task reports. If this is false, the controller exits immediately after finishing the query.
Code relying on monomorphic processing on JDK8 doesn't work correctly, since it tries to reference getArrayLength using method handles, which might have been accidentally removed here since it seems unused. This PR adds the method back as is.
Fixes a bug caused by #14919, which was just using the column name as part of a temp file name, which.. isn't very cool, my bad. Switched to use StringUtils.urlEncode so that ugly chars don't explode stuff. The modified test fails without the changes in this PR.
Row-based frames, and by extension, MSQ now supports numeric array types. This means that all queries consuming or producing arrays would also work with MSQ. Numeric arrays can also be ingested via MSQ. Post this patch, queries like, SELECT [1, 2] would work with MSQ since they consume a numeric array, instead of failing with an unsupported column type exception.
When merging analyses, lenient merging sets unmergeable aggregators
to null. Merging such a null aggregator record into a nonnull record
would potentially lead to NPE in getMergingFactory.
The new code only calls getMergingFactory if both the old and new
aggregators are nonnull; else, if either is null, then the merged
aggregator is also set to null.
This patch introduces "processor managers" to processor factories, as a replacement for the sequence of processors. Processor managers can use the results of earlier processors to influence the creation of later processors, which provides us with the building block we need to ensure that broadcast join data is only read once.
In particular, when broadcast join is happening, the BaseFrameProcessorFactory now uses a ChainedProcessorManager to first run BroadcastJoinSegmentMapFnProcessor (in a single thread), and then run all of the regular processors (possibly multithreaded).
When moving timestamps by an offset using org.joda.time.chrono.ISOChronology library, if the new timestamp falls in Daylight Savings Time (DST) transition period, the library rounds it off to the nearest valid time. This can lead to incorrect final timestamp when calculated using intermediate offsets landing in DST transition, for e.g. +21D arrived at using +14D and +7D offset, where +14D lands in DST transition period. Since bucketStart values are calculated using this library, this behaviour can lead to incorrect bucketStart times.
This change updates dependencies as needed and fixes tests to remove code incompatible with Java 21
As a result all unit tests now pass with Java 21.

* explain why we need to override configuration when specifying outputFile
* remove configuration from dependency management in favor of explicit overrides in each module.

* continue using latest mockito 4.x (4.11.0) when running with Java 8
* remove need to mock private fields
* exclude incorrectly declared mockito dependency from pac4j-oidc
* remove mocking of ByteBuffer, since sealed classes can no longer be mocked in Java 21
* add JVM options workaround for system-rules junit plugin not supporting Java 18+
* exclude older versions of byte-buddy from assertj-core
* fix for Java 19 changes in floating point string representation
