Fix round robining in router. (#5500)
* Fix round robining in router.

Say that ten times fast.

For query endpoints, AsyncQueryForwardingServlet called hostFinder.getDefaultServer()
to set a default server, followed by hostFinder.getServer(inputQuery) to override it
with query-specific routing. Since hostFinder is round-robin, this skips a server.
When there are only two servers, one server is _always_ skipped and the router sends
all queries to the same broker.

* Adjust spacing.

SegmentMetadataQuery: Fix default interval handling. (#5489)
* SegmentMetadataQuery: Fix default interval handling.

PR #4131 introduced a new copy builder for segmentMetadata that did
not retain the value of usingDefaultInterval. This led to it being
dropped and the default-interval handling not working as expected.
Instead of using the default 1 week history when intervals are not
provided, the segmentMetadata query would query _all_ segments,
incurring an unexpected performance hit.

This patch fixes the bug and adds a test for the copy builder.

Fix two improper casts in HavingSpecMetricComparator. (#5352)
* Fix two improper casts in HavingSpecMetricComparator.

Fixes two things:

1. An improper double-to-long cast when comparing double metrics to any
   kind of value, which was a regression from #4883.
2. An improper double-to-long cast when comparing a long/int metric to a
   double/float value: the value was cast to long/int, drawing strange
   conclusions like int 100 matching a havingSpec of equalTo(100.5).

Properly set "identity" in query metrics. (#5330)
* Properly set "identity" in query metrics.

This patch adds an "identity" field to QueryPlus and sets it in
QueryLifecycle when the query starts executing. This is important
because it allows it to be used for future QueryMetrics created
by that QueryPlus object.

We also add "identity" to the request-level QueryMetrics object
created in emitLogsAndMetrics.

2. One JVM could partially write a file, then crash, leaving a truncated file.

Lookups: Inherit "injective" from registered lookups, improve docs. (#5316)
Code changes:
- In the lookup-based extractionFns, inherit injective property from
  the lookup itself if not specified.

Doc changes:
- Add a "Query execution" section to the lookups doc explaining how
  injective lookups and their optimizations work.
- Remove scary warnings against using registeredLookup extractionFns.
  They are necessary and important since they work with filters and
  function cascades -- two things that the dimension specs do not do.
  They deserve to be first class citizens.
- Move the "registeredLookup" fn above the "lookup" fn. It's probably
  more commonly used, so the docs read better this way.

changes:

* introduces a new abstract query type `TimeBucketedQuery` for all queries which have a `Granularity` (100% not attached to this name). `GroupByQuery`, `SearchQuery`, `SelectQuery`, `TimeseriesQuery`, and `TopNQuery` all extend `TimeBucke
tedQuery`, cutting down on some duplicate code and providing a mechanism for `TimewarpOperator` (and anything else) that needs to be aware of granularity

Gian Merlino 77df5e0673 ExpressionSelectors: Add optimized selectors. (#5048)
* ExpressionSelectors: Add caching selectors.

- SingleLongInputCaching selector for expressions on the __time column,
  using a similar optimization to SingleScanTimeDimSelector
- SingleStringInputDimensionSelector for expressions on string columns
  that return strings, using a similar optimization to ExtractionFn
  based DimensionSelectors.
- SingleStringInputCaching selector for expressions on string columns
  that return primitives.

Also, in the SQL planner, prefer expressions for time operations
rather than extractionFns.

* Code review comments.

* Fix havingSpec on complex aggregators.

- Uses the technique from #4883 on DimFilterHavingSpec too.
- Also uses Transformers from #4890, necessitating a move of that and other
  related classes from druid-server to druid-processing. They probably make
  more sense there anyway.
- Adds a SQL query test.

Fixes #4957.

* Fix improper handling of empty arrays in StringDimensionIndexer.

This bug was able to introduce data errors: if the input rows to an
IncrementalIndex contained entirely empty arrays and single values, then
upon persisting to disk, the empty arrays would be replaced with the
lexicographically smallest single value, rather than nulls like they
should have been.

* Style fix.

* Add tests for bitmap indexes too.

Gian Merlino b20e3038b6 SQL: Upgrade to Calcite 1.14.0, some refactoring of internals. (#4889)
* SQL: Upgrade to Calcite 1.14.0, some refactoring of internals.

This brings benefits:
- Ability to do GROUP BY and ORDER BY with ordinals.
- Ability to support IN filters beyond 19 elements (fixes #4203).

Some refactoring of druid-sql internals:
- Builtin aggregators and operators are implemented as SqlAggregators
  and SqlOperatorConversions rather being special cases. This simplifies
  the Expressions and GroupByRules code, which were becoming complex.
- SqlAggregator implementations are no longer responsible for filtering.

Added new functions:
- Expressions: strpos.
- SQL: TRUNCATE, TRUNC, LENGTH, CHAR_LENGTH, STRLEN, STRPOS, SUBSTR,
  and DATE_TRUNC.

* Add missing @Override annotation.

* Adjustments for forbidden APIs.
