Scan: Add "orderBy" parameter. (#11930)
* Scan: Add "orderBy" parameter.

This patch adds an API for requesting non-time orderings, although it
does not actually add the ability to execute such queries.

The changes are done in such a way that no matter how Scan query objects
are constructed, they will have a correct "getOrderBy". This will enable
us to switch the execution to exclusively use "getOrderBy" later on when
it's implemented.

Scan queries are serialized such that they only include "order" (time
order) if the ordering is time-based, and they only include "orderBy" if
the ordering is non-time-based. This maximizes compatibility with
the existing API while also providing a clean look for formatted queries.

Because this patch does not include execution logic, if someone actually
tries to run a query with non-time ordering, then they will get an error
like "Cannot execute query with orderBy [quality ASC]".

* SQL module fixes.

* Add spotbugs-exclude.

* Remove unused method.

Fix incorrect comparison in RowSignature. (#11905)
PR #11882 introduced a type comparison using ==, but while it was in flight,
another PR #11713 changed the type enum to a class. So the comparison should
properly be done with "equals".

Make subquery IDs more comprehensive (#11809)
There are 3 types of query IDs - id, subQueryId, sqlQueryId. Currently, whenever a query generates subqueries, the subquery's subQueryId is populated randomly. Also, subquery's Id is not set to the parent query Id. Therefore there is no way of linking the subqueries to the parent query, and one loses the ability to look at end to end view of the query.

This PR aims to implement following couple of things:

Populate the subqueries with it's parent's id (and sqlQueryId if present)
Populate the subqueryId such that it forms a hierarchical relationship amongs themselves. For example, if there is a query which launches a subquery, which in turn launches a couple of subqueries, then the ids and subQueryIds should have following structure.

RowBasedSegment: Use Sequence instead of Iterable. (#11886)
* RowBasedSegment: Use Sequence instead of Iterable.

The main reason this is good is that Sequences can include baggage that
must be closed after iteration is finished. This enables creating
RowBasedSegments on top of closeable sequences of rows.

To preserve the optimization that allows reversing a List without
copying it, this patch also makes SimpleSequence its own class and allows
extracting the Iterable that was used to create it.

* Fix tests.

HashJoinEngine: Fix extraneous advance of left cursor. (#11890)
This could happen for right or full outer joins in certain cases. Tests
weren't catching this because existing Cursor implementations generally
ignore extraneous calls to "advance". So, to help catch this in tests,
extra state validations are also added to RowWalker, which is used by
RowBasedSegment.

RowBasedCursor: Add column-value-reuse optimization. (#11884)
* RowBasedCursor: Add column-value-reuse optimization.

Most of the logic is in RowBasedColumnSelectorFactory, although in this
patch its only user is RowBasedCursor. This improves performance of
features that use RowBasedSegment, like lookup and inline datasources.
It's especially helpful for inline datasources that contain lengthy
arrays, due to the fact that the transformed array can be reused.

* Changes from code review.

* Fixes for ColumnCapabilitiesImplTest.

Remove OffheapIncrementalIndex and clarify aggregator thread-safety needs. (#11124)
* Remove OffheapIncrementalIndex and clarify aggregator thread-safety needs.

This patch does the following:

- Removes OffheapIncrementalIndex.
- Clarifies that Aggregators are required to be thread safe.
- Clarifies that BufferAggregators and VectorAggregators are not
  required to be thread safe.
- Removes thread safety code from some DataSketches aggregators that
  had it. (Not all of them did, and that's OK, because it wasn't necessary
  anyway.)
- Makes enabling "useOffheap" with groupBy v1 an error.

Rationale for removing the offheap incremental index:

- It is only used in one rare scenario: groupBy v1 (which is non-default)
  in "useOffheap" mode (also non-default). So you have to go pretty deep
  into the wilderness to get this code to activate in production. It is
  never used during ingestion.
- Its existence complicates developer efforts to reason about how
  aggregators get used, because the way it uses buffer aggregators is so
  different from how every other query engine uses them.
- It doesn't have meaningful testing.

By the way, I do believe that the given way the offheap incremental index
works, it actually didn't require buffer aggregators to be thread-safe.
It synchronizes on "aggregate" and doesn't call "get" until it has
stopped calling "aggregate". Nevertheless, this is a bother to think about,
and for the above reasons I think it makes sense to remove the code anyway.

* Remove things that are now unused.

* Revert removal of getFloat, getLong, getDouble from BufferAggregator.

* OAK-related warnings, suppressions.

* Unused item suppressions.

Remove CloseQuietly and migrate its usages to other methods. (#10247)
* Remove CloseQuietly and migrate its usages to other methods.

These other methods include:

1) New method CloseableUtils.closeAndWrapExceptions, which wraps IOExceptions
   in RuntimeExceptions for callers that just want to avoid dealing with
   checked exceptions. Most usages were migrated to this method, because it
   looks like they were mainly attempts to avoid declaring a throws clause,
   and perhaps were unintentionally suppressing IOExceptions.
2) New method CloseableUtils.closeInCatch, designed to properly close something
   in a catch block without losing exceptions. Some usages from catch blocks
   were migrated here, when it seemed that they were intended to avoid checked
   exception handling, and did not really intend to also suppress IOExceptions.
3) New method CloseableUtils.closeAndSuppressExceptions, which sends all
   exceptions to a "chomper" that consumes them. Nothing is thrown or returned.
   The behavior is slightly different: with this method, _all_ exceptions are
   suppressed, not just IOExceptions. Calls that seemed like they had good
   reason to suppress exceptions were migrated here.
4) Some calls were migrated to try-with-resources, in cases where it appeared
   that CloseQuietly was being used to avoid throwing an exception in a finally
   block.

Enable routing of SQL queries at Router (#11566)
This PR adds a new property druid.router.sql.enable which allows the
Router to handle SQL queries when set to true.

This change does not affect Avatica JDBC requests and they are still routed
by hashing the Connection ID.

To allow parsing of the request object as a SqlQuery (contained in module druid-sql),
some classes have been moved from druid-server to druid-services with
the same package name.

Make SegmentLoader extensible and customizable (#11398)
This PR refactors the code related to segment loading specifically SegmentLoader and SegmentLoaderLocalCacheManager. SegmentLoader is marked UnstableAPI which means, it can be extended outside core druid in custom extensions. Here is a summary of changes

SegmentLoader returns an instance of ReferenceCountingSegment instead of Segment. Earlier, SegmentManager was wrapping Segment objects inside ReferenceCountingSegment. That is now moved to SegmentLoader. With this, a custom implementation can track the references of segments. It also allows them to create custom ReferenceCountingSegment implementations. For this reason, the constructor visibility in ReferenceCountingSegment is changed from private to protected.
SegmentCacheManager has two additional methods called - reserve(DataSegment) and release(DataSegment). These methods let the caller reserve or release space without calling SegmentLoader#getSegment. We already had similar methods in StorageLocation and now they are available in SegmentCacheManager too which wraps multiple locations.
Refactoring to simplify the code in SegmentCacheManager wherever possible. There is no change in the functionality.

Replace Processing ExecutorService with QueryProcessingPool (#11382)
This PR refactors the code for QueryRunnerFactory#mergeRunners to accept a new interface called QueryProcessingPool instead of ExecutorService for concurrent execution of query runners. This interface will let custom extensions inject their own implementation for deciding which query-runner to prioritize first. The default implementation is the same as today that takes the priority of query into account. QueryProcessingPool can also be used as a regular executor service. It has a dedicated method for accepting query execution work so implementations can differentiate between regular async tasks and query execution tasks. This dedicated method also passes the QueryRunner object as part of the task information. This hook will let custom extensions carry any state from QuerySegmentWalker to QueryProcessingPool#mergeRunners which is not possible currently.

Fix vectorized cardinality bug on certain string columns. (#11199)
* Fix vectorized cardinality bug on certain string columns.

Fixes a bug introduced in #11182, related to the fact that in some cases,
ColumnProcessors.makeVectorProcessor will call "makeObjectProcessor"
instead of "makeSingleValueDimensionProcessor" or
"makeMultiValueDimensionProcessor". CardinalityVectorProcessorFactory
improperly ignored calls to "makeObjectProcessor".

In addition to fixing the bug, I added this detail to the javadocs for
VectorColumnProcessorFactory, to prevent others from running into the
same thing in the future. They do not currently call out this case.

* Improve test coverage.

* Additional fixes.

Vectorize the cardinality aggregator. (#11182)
* Vectorize the cardinality aggregator.

Does not include a byRow implementation, so if byRow is true then
the aggregator still goes through the non-vectorized path.

Testing strategy:

- New tests that exercise both styles of "aggregate" for supported types.
- Some existing tests have also become active (note the deleted
  "cannotVectorize" lines).

* Adjust whitespace.

InDimFilter: Fix cache key computation to avoid collisions. (#11168)
The prior code did not include separation between values, and encoded
null ambiguously. This patch fixes both of those issues by encoding
strings as length + value instead of just value.

I think cache key computation was OK prior to #9800. Prior to that
patch, the cache key was computed using CacheKeyBuilder.appendStrings,
which encodes strings as UTF-8 and inserts a separator byte (0xff)
between them that cannot appear in a UTF-8 stream.

InDimFilter: Fix NPE involving certain Set types. (#11169)
* InDimFilter: Fix NPE involving certain Set types.

Normally, InDimFilters that come from JSON have HashSets for "values".
However, programmatically-generated filters (like the ones from #11068)
may use other set types. Some set types, like TreeSets with natural
ordering, will throw NPE on "contains(null)", which causes the
InDimFilter's ValueMatcher to throw NPE if it encounters a null value.

This patch adds code to detect if the values set can support
contains(null), and if not, wrap that in a null-checking lambda.

Also included:

- Remove unneeded NullHandling.needsEmptyToNull method.
- Update IndexedTableJoinable to generate a TreeSet that does not
  require lambda-wrapping. (This particular TreeSet is how I noticed
  the bug in the first place.)

* Test fixes.

Enable rewriting certain inner joins as filters. (#11068)
* Enable rewriting certain inner joins as filters.

The main logic for doing the rewrite is in JoinableFactoryWrapper's
segmentMapFn method. The requirements are:

- It must be an inner equi-join.
- The right-hand columns referenced by the condition must not contain any
  duplicate values. (If they did, the inner join would not be guaranteed
  to return at most one row for each left-hand-side row.)
- No columns from the right-hand side can be used by anything other than
  the join condition itself.

HashJoinSegmentStorageAdapter is also modified to pass through to
the base adapter (even allowing vectorization!) in the case where 100%
of join clauses could be rewritten as filters.

In support of this goal:

- Add Query getRequiredColumns() method to help us figure out whether
  the right-hand side of a join datasource is being used or not.
- Add JoinConditionAnalysis getRequiredColumns() method to help us
  figure out if the right-hand side of a join is being used by later
  join clauses acting on the same base.
- Add Joinable getNonNullColumnValuesIfAllUnique method to enable
  retrieving the set of values that will form the "in" filter.
- Add LookupExtractor canGetKeySet() and keySet() methods to support
  LookupJoinable in its efforts to implement the new Joinable method.
- Add "enableRewriteJoinToFilter" feature flag to
  JoinFilterRewriteConfig. The default is disabled.

* Test improvements.

* Test fixes.

* Avoid slow size() call.

* Remove invalid test.

test, since its behavior and correctness depends on whether it runs before

DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.

* Various fixups.

* Uncomment incorrectly commented lines.

* Move TransformSpecTest to the proper module.

* Add druid.indexer.task.ignoreTimestampSpecForDruidInputSource setting.

Fix runtime error when IndexedTableJoinMatcher matches long selector to unique string index. (#10942)
* Fix runtime error when IndexedTableJoinMatcher matches long selector to unique string index.

The issue arises when matching against a long selector on the left-hand side to a string
typed Index on the right-hand side, and when that Index also returns true from areKeysUnique.
In this case, IndexedTableJoinMatcher would generate a ConditionMatcher that implements
matchSingleRow by calling findUniqueLong on the Index. This is inappropriate because the Index
is actually string typed. The fix is to check the type of the Index before deciding how to
implement the ConditionMatcher.

The patch adds "testMatchSingleRowToUniqueStringIndex" to IndexedTableJoinMatcherTest, which
explores this case.

Retain order of AND, OR filter children. (#10758)
* Retain order of AND, OR filter children.

If we retain the order, it enables short-circuiting. People can put a
more selective filter earlier in the list and lower the chance that
later filters will need to be evaluated.

Short-circuiting was working before #9608, which switched to unordered
sets to solve a different problem. This patch tries to solve that
problem a different way.

This patch moves filter simplification logic from "optimize" to
"toFilter", because that allows the code to be shared with Filters.and
and Filters.or. The simplification has become more complicated and so
it's useful to share it.

This patch also removes code from CalciteCnfHelper that is no longer
necessary because Filters.and and Filters.or are now doing the work.

* Fixes for inspections.

* Fix tests.

* Back to a Set.

RowBasedIndexedTable: Add specialized index types for long keys. (#10430)
* RowBasedIndexedTable: Add specialized index types for long keys.

Two new index types are added:

1) Use an int-array-based index in cases where the difference between
   the min and max values isn't too large, and keys are unique.

2) Use a Long2ObjectOpenHashMap (instead of the prior Java HashMap) in
   all other cases.

In addition:

1) RowBasedIndexBuilder, a new class, is responsible for picking which
   index implementation to use.

2) The IndexedTable.Index interface is extended to support using
   unboxed primitives in the unique-long-keys case, and callers are
   updated to use the new functionality.

Other key types continue to use indexes backed by Java HashMaps.

* Fixup logic.

* Add tests.

Fix stringFirst/stringLast rollup during ingestion (#10332)
* Add IndexMergerRollupTest

This changelist adds a test to merge indexes with StringFirst/StringLast aggregator.

* Fix StringFirstAggregateCombiner/StringLastAggregateCombiner

The segment-level type for stringFirst/stringLast is SerializablePairLongString,
not String. This changelist fixes it.

* Fix EarliestLatestAnySqlAggregator to handle COMPLEX type

This changelist allows EarliestLatestAnySqlAggregator to accept COMPLEX
type as an operand. For its return type, we set it to VARCHAR, since
COMPLEX column is only generated by stringFirst/stringLast during ingestion
rollup.

* Return value with smaller timestamp in StringFirstAggregatorFactory.combine function

* Add integration tests for stringFirst/stringLast during ingestion

* Use one EarliestLatestReturnTypeInference instance

Fix handling of 'join' on top of 'union' datasources. (#10318)
* Fix handling of 'join' on top of 'union' datasources.

The problem is that unions are typically rewritten into a series of
individual queries on the underlying tables, but this isn't done when
the union is wrapped in a join.

The main changes are in UnionQueryRunner:

1) Replace an instanceof UnionQueryRunner check with DataSourceAnalysis.
2) Replace a "query.withDataSource" call with a new function, "Queries.withBaseDataSource".

Together, these enable UnionQueryRunner to "see through" a join.

* Tests.

* Adjust heap sizes for integration tests.

* Different approach, more tests.

* Tweak.

* Styling.
