This change removes ListenableFutures.transformAsync in favor of the
existing Guava Futures.transform implementation. Our own implementation
had a bug which did not fail the future if the applied function threw an
exception, resulting in the future never completing.
An attempt was made to fix this bug, however when running againts Guava's own
tests, our version failed another half dozen tests, so it was decided to not
continue down that path and scrap our own implementation.
Explanation for how was this bug manifested itself:
An exception thrown in BaseAppenderatorDriver.publishInBackground when
invoked via transformAsync in StreamAppenderatorDriver.publish will
cause the resulting future to never complete.
This explains why when encountering https://github.com/apache/druid/issues/9845
the task will never complete, forever waiting for the publishFuture to
register the handoff. As a result, the corresponding "Error while
publishing segments ..." message only gets logged once the index task
times out and is forcefully shutdown when the future is force-cancelled
by the executor.
* - GroupByQueryEngineV2: Fix leak of intermediate processing buffer when
exceptions are thrown before result sequence is created.
- PooledTopNAlgorithm: Fix leak of intermediate processing buffer when
exceptions are thrown before the PooledTopNParams object is created.
- BlockingPool: Remove unused "take" methods.
* Add tests to verify that buffers have been returned.
* Fix various Yielder leaks.
- CombiningSequence leaked the input yielder from "toYielder" if it ran
into an exception while accumulating the last value from the input
yielder.
- MergeSequence leaked input yielders from "toYielder" if it ran into
an exception while building the initial priority queue.
- ScanQueryRunnerFactory leaked the input yielder in its
"priorityQueueSortAndLimit" strategy if it ran into an exception
while scanning and sorting.
- YieldingSequenceBase.accumulate chomped IOExceptions thrown in
"accumulate" during yielder closing.
* Add tests.
* Fix braces.
* Number based columns representing time in custom format cannot be used as timestamp column in Druid.
Prior to this fix, if an integer column in parquet is storing dateint in format yyyyMMdd, it cannot be used as timestamp column in Druid as the timestamp parser interprets it as a number storing UTC time instead of treating it as a number representing time in yyyyMMdd format. Data formats like TSV or CSV don't suffer from this problem as the timestamp is passed in an as string which the timestamp parser is able to parse correctly.

* SQL: More straightforward handling of join planning.
Two changes that simplify how joins are planned:
1) Stop using JoinProjectTransposeRule as a way of guiding subquery
removal. Instead, add logic to DruidJoinRule that identifies removable
subqueries and removes them at the point of creating a DruidJoinQueryRel.
This approach reduces the size of the planning space and allows the
planner to complete quickly.
2) Remove rules that reorder joins. Not because of an impact on the
planning time (it seems minimal), but because the decisions that the
planner was making in the new tests were sometimes worse than the
user-provided order. I think we'll need to go with the user-provided
order for now, and revisit reordering when we can add more smarts to
the cost estimator.
A third change updates numeric ExprEval classes to store their
value as a boxed type that corresponds to what it is supposed to be.
This is useful because it affects the behavior of "asString", and
is included in this patch because it is needed for the new test
"testInnerJoinTwoLookupsToTableUsingNumericColumnInReverse". This
test relies on CAST('6', 'DOUBLE') stringifying to "6.0" like an
actual double would.
Fixes#9646.

- remove redundant escapes
- performance warnings
- access static member via instance reference
- static method declared final
- inner class may be static
Most of these changes are aesthetic, however, they will allow inspections to
be enabled as part of CI checks going forward
The valuable changes in this delta are:
- using StringBuilder instead of string addition in a loop
indexing-hadoop/.../Utils.java
processing/.../ByteBufferMinMaxOffsetHeap.java
- Use class variables instead of static variables for parameterized test
processing/src/.../ScanQueryLimitRowIteratorTest.java
* Add intelliJ inspection warnings as errors to druid profile
* one more static inner class
* Make JoinableFactory an extension point
This change makes it so that extensions can register a JoinableFactory that
should be used for a DataSource.
Extensions can provide the factories via DruidBinders#joinableFactoryBinder
Known DataSources - like InlineDataSource are provided in the
JoinableFactoryModule. This module installs a FactoryWarehouse that is
used to decide which factory should be used to generate the Joinable for
the provided DataSource.
The ExtensionPoint is marked as Beta since it is not yet clear if this
needs to remain available to other extensions or if the best way to
register a factory is by using the datasource class.
* Add module test
* remove useless bindings in test
* remove ExtensionPoint annotation
* Make LifecycleLock not final to help with testing
* Reconcile terminology and method naming to 'used/unused segments'; Don't use terms 'enable/disable data source'; Rename MetadataSegmentManager to MetadataSegments; Make REST API methods which mark segments as used/unused to return server error instead of an empty response in case of error
