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.
* timewarp and timezones
changes:
* `TimewarpOperator` will now compensate for daylight savings time shifts between date translation ranges for queries using a `PeriodGranularity` with a timezone defined
* 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
* move precondition check to TimeBucketedQuery, add Granularities.nullToAll, add getTimezone to TimeBucketQuery
* formatting
* more formatting
* unused import
* changes:
* add 'getGranularity' and 'getTimezone' to 'Query' interface
* merge 'TimeBucketedQuery' into 'BaseQuery'
* fixup tests from resulting serialization changes
* dedupe
* fix after merge
* suppress warning
* Apply 'power of 2' optimization to BlockLayoutIndexedDoubleSupplier; slight optimization of buffer.get() in block layout indexed suppliers
* Fix byte order
* Deduplicate DataSegments contents (loadSpec's keys, dimensions and metrics lists as a whole) more aggressively; use ArrayMap instead of default LinkedHashMap for DataSegment.loadSpec, because they have only 3 entries on average; prune DataSegment.loadSpec on brokers
* Fix DataSegmentTest
* Refinements
* Try to fix
* Fix the second DataSegmentTest
* Nullability
* Fix tests
* Fix tests, unify to use TestHelper.getJsonMapper()

* support reindexing
* implemented suggestions from jihoonson
* style fix
* use max(k, other.k) for better accuracy
* check for NilColumnValueSelector instead of null
* throw exceptions instead of providing no-op comparators
* SQL: Improve translation of time floor expressions.
The main change is to TimeFloorOperatorConversion.applyTimestampFloor.
- Prefer timestamp_floor expressions to timeFormat extractionFns, to
avoid turning things into strings when it isn't necessary.
- Collapse CAST(FLOOR(X TO Y) AS DATE) to FLOOR(X TO Y) if appropriate.
* Fix tests.
* 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.
* maxQueryTimeout property in runtime properties.
* extra line
* move withTimeoutAndMaxScatterGatherBytes method to QueryLifeCycle.
* Fix initialize method.
* remove unused import.
* doc update.
* some more details in doc about query failure..
* minor fix.
* decorating QueryRunner to set and verify context. Added by servers.
* remove whitespace.
* SQL: Improved behavior when implicitly casting strings to date/time literals.
- Handle all flavors of ISO8601 and SQL literals.
- Throw errors on other literals instead of silently transforming them to 0.
* Respect timeZone when format is null.

* add control for custom ordering and type
* update doc
* fix compile
* fix compile
* add segments param
* fix serde error
* fix build
* 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.
* Remove unused import.
* 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.
* Introduce System wide property to select how to store double.
Set the default to store as float

* QueryableIndexStorageAdapter: Lift column cache to Cursor sequence.
This is where it was before #4710, when its was moved to the individual
Cursors, leading to higher than expected memory usage. It could be
extreme for finer query granularities like "second".
* Comment.
* 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.
