The main one is updating datasources.md to talk about SQL. (It still said
that table unions are not supported in SQL.) Also, this doc update adds
some clarifying details on limitations.
* 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.

PR #10936 renamed BitmapBenchmark, the parent of a couple of bitmap tests, to
BitmapOperationTest. This patch renames it to BitmapOperationTestBase so JUnit
doesn't pick it up as a test case. When JUnit picks it up, it becomes a flaky
test, since its behavior and correctness depends on whether it runs before
or after its subclasses.
Regression introduced in #11004 due to overzealous optimization. Even though
we replaced stateful usage of ByteBuffer with stateless usage of Memory, we
still need to create a new object on "duplicate" due to semantics of setBuffer.

* DataSchema: Improve duplicate-column error message.
Now, when duplicate columns are specified, the error message will include
information about where those duplicate columns were seen. Also, if there
are multiple duplicate columns, all will be listed in the error message
instead of just the first one encountered.
* Fix style for checkstyle.
* Further improve error message.
* fix nested groupby got empty result when using virtual column
* move to query.getVirtualColumns().wrap instead of new VirtualizedColumnSelectorFactory
* move test to GroupByQueryRunnerTest
* Update processing/src/test/java/org/apache/druid/query/groupby/GroupByQueryRunnerTest.java

* Add paramter to loadstatus API to compute underdeplication against cluster view
This change adds a query parameter `computeUsingClusterView` to loadstatus apis
that if specified have the coordinator compute undereplication for segments based
on the number of services available within cluster that the segment can be replicated
on, instead of the configured replication count configured in load rule. A default
load rule is created in all clusters that specified that all segments should be
replicated 2 times. As replicas are forced to be on separate nodes in the cluster,
this causes the loadstatus api to report that there are under-replicated segments
when there is only 1 data server in the cluster. In this case, calling loadstatus
api without this new query parameter will always result in a response indicating
under-replication of segments
