* 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

* SQL support for union datasources.
Exposed via the "UNION ALL" operator. This means that there are now two
different implementations of UNION ALL: one at the top level of a query
that works by concatenating subquery results, and one at the table level
that works by creating a UnionDataSource.
The SQL documentation is updated to discuss these two use cases and how
they behave.
Future work could unify these by building support for a native datasource
that represents the union of multiple subqueries. (Today, UnionDataSource
can only represent the union of tables, not subqueries.)

* Add SQL "OFFSET" clause.
Under the hood, this uses the new offset features from #10233 (Scan)
and #10235 (GroupBy). Since Timeseries and TopN queries do not currently
have an offset feature, SQL planning will switch from one of those to
Scan or GroupBy if users add an OFFSET.
Includes a refactoring to harmonize offset and limit planning using an
OffsetLimit wrapper class. This is useful because it ensures that the
various places that need to deal with offset and limit collapsing all
behave the same way, using its "andThen" method.

* ROUND and having comparators correctly handle doubles
Double.NaN, Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY are not real
numbers. Because of this, they can not be converted to BigDecimal and instead
throw a NumberFormatException.
This change adds support for calculations that produce these numbers either
for use in the `ROUND` function or the HavingSpecMetricComparator by not
attempting to convert the number to a BigDecimal.
The bug in ROUND was first introduced in #7224 where we added the ability to
round to any decimal place. This PR changes the behavior back to using
`Math.round` if we recognize a number that can not be converted to a
BigDecimal.

(previously, they threw errors).

non-literal patterns.

* Refactor JoinFilterAnalyzer
This patch attempts to make it easier to follow the join filter analysis code
with the hope of making it easier to add rewrite optimizations in the future.
To keep the patch small and easy to review, this is the first of at least 2
patches that are planned.
This patch adds a builder to the Pre-Analysis, so that it is easier to
instantiate the preAnalysis. It also moves some of the filter normalization
code out to Fitlers with associated tests.
* fix tests
* Refactor JoinFilterAnalyzer - part 2
This change introduces the following components:
* RhsRewriteCandidates - a wrapper for a list of candidates and associated
functions to operate on the set of candidates.
* JoinableClauses - a wrapper for the list of JoinableClause that represent
a join condition and the associated functions to operate on the clauses.
* Equiconditions - a wrapper representing the equiconditions that are used
in the join condition.
And associated test changes.
This refactoring surfaced 2 bugs:
- Missing equals and hashcode implementation for RhsRewriteCandidate, thus
allowing potential duplicates in the rhs rewrite candidates
- Missing Filter#supportsRequiredColumnRewrite check in
analyzeJoinFilterClause, which could result in UnsupportedOperationException
being thrown by the filter
* fix compile error
* remove unused class
* Refactor JoinFilterAnalyzer - Correlations
Move the correlation related code out into it's own class so it's easier
to maintain.
Another patch should follow this one so that the query path uses the
correlation object instead of it's underlying maps.
* Optimize join queries where filter matches nothing
Fixes#9787
This PR changes the Joinable interface to return an Optional set of correlated
values for a column.
This allows the JoinFilterAnalyzer to differentiate between the case where the
column has no matching values and when the column could not find matching
values.
This PR chose not to distinguish between cases where correlated values could
not be computed because of a config that has this behavior disabled or because
of user error - like a column that could not be found. The reasoning was that
the latter is likely an error and the non filter pushdown path will surface the
error if it is.
* Add ingestion specs for CalciteQueryTests
This PR introduces ingestion specs that can be used for local testing
so that CalciteQueryTests can be built on a druid cluster.
