Gian Merlino d4ef0f6d94 Improved SQL support for floats and doubles. (#4598)

  and DECIMAL.
- Use float* aggregators when appropriate.
- Add tests involving both float and double columns.
- Adjust documentation accordingly.

* CR comments.

* Fix braces.

Gian Merlino 16817e408d SQL + Expressions = Best friends forever. (#4360)
* SQL + Expressions = Best friends forever.

- Use expressions as a projection layer for anything that can't be
  expressed using traditional Druid extractionFns. Sometimes they're
  embedded directly (like "expression" filters, builtin aggregators,
  or "expression" post-aggregators). Sometimes they're referenced
  through virtual columns (like dimensionSpecs, which can't innately
  reference functions of more than one column without the virtual
  column layer).
- Add many new functions and operators, taking advantage of the
  expression capability (see the querying/sql.md doc).
- Improve consistency of constant reduction and of casting by
  using Druid expressions for this instead of Calcite's RexExecutor.

* Fix casting bug, and other code review comments.

* Fix docs.

Gian Merlino 4ca5270e88 Ignore chunkPeriod for groupBy v2, fix chunkPeriod for irregular periods. (#4004)
* Ignore chunkPeriod for groupBy v2, fix chunkPeriod for irregular periods.

Includes two fixes:
- groupBy v2 now ignores chunkPeriod, since it wouldn't have helped anyway (its mergeResults
returns a lazy sequence) and it generates incorrect results.
- Fix chunkPeriod handling for periods of irregular length, like "P1M" or "P1Y".

Also includes doc and test fixes:
- groupBy v1 was no longer being tested by GroupByQueryRunnerTest since #3953, now it
  is once again.
- chunkPeriod documentation was misleading due to its checkered past. Updated it to
  be more accurate.

* Remove unused import.

* Restore buffer size.

Gian Merlino 16ef513c7d SQL: Add context and contextual functions to planner. (#3919)
* SQL: Add context and contextual functions to planner.

Added support for context parameters specified as JDBC connection properties
or a JSON object for SQL-over-JSON-over-HTTP.

Also added features that depend on context functionality:

- Added CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP functions.
- Added support for time zones other than UTC via a "timeZone" context.
- Pass down query context to Druid queries too.

Also some bug fixes:

- Fix DATE handling, it was largely done incorrectly before.
- Fix CAST(__time TO DATE) which should do a floor-to-day.
- Fix non-equality comparisons to FLOOR(__time TO X).
- Fix maxQueryCount property.

* Pass down context to nested queries too.

Gian Merlino d51f5e058d SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators. (#3852)
* SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators.

Switched from CalciteConnection to Planner, bringing benefits:

- CalciteConnection's JDBC interface no longer sits between the SQL server
  (HTTP/Avatica) and Druid's query layer. Instead, the SQL servers can use
  Druid Sequence objects directly, reducing overhead in the query return path.

- Implemented our own Planner-based Avatica Meta, letting us control
  connection timeouts and connection / statement limits. The previous
  CalciteConnection-based implementation didn't have any limits or timeouts.

- The Planner interface lets us override the operator table, opening up
  SQL language extensions. This patch includes two: APPROX_COUNT_DISTINCT
  in core, and a QUANTILE aggregator in the druid-histogram extension.

Also:

- Added INFORMATION_SCHEMA metadata schema.

- Added tests for Unicode literals and escapes.

* Verify statement is actually open before closing it.

* More detailed INFORMATION_SCHEMA docs.

Contrast with approximate count distinct, which is:

  SELECT COUNT(DISTINCT col) FROM druid.foo

* Add deeply-nested groupBy docs, tests, and maxQueryCount config.

* Extract magic constants into statics.

* Rework rules to put preconditions in the "matches" method.

Gian Merlino 21bce96c4c More useful query errors. (#3335)
Follow-up to #1773, which meant to add more useful query errors but
did not actually do so. Since that patch, any error other than
interrupt/cancel/timeout was reported as `{"error":"Unknown exception"}`.

With this patch, the error fields are:

- error, one of the specific strings "Query interrupted", "Query timeout",
  "Query cancelled", or "Unknown exception" (same behavior as before).
- errorMessage, the message of the topmost non-QueryInterruptedException
  in the causality chain.
- errorClass, the class of the topmost non-QueryInterruptedException
  in the causality chain.
- host, the host that failed the query.

Gian Merlino 2553997200 Associate groupBy v2 resources with the Sequence lifecycle. (#3296)

are never freed.

Also simplifies how groupBy handles config overrides (this made the new

Gian Merlino fdc7e88a7d Allow queries with no aggregators. (#3216)
This is actually reasonable for a groupBy or lexicographic topNs that is
being used to do a "COUNT DISTINCT" kind of query. No aggregators are
needed for that query, and including a dummy aggregator wastes 8 bytes
per row.

It's kind of silly for timeseries, but why not.

Gian Merlino 4cc39b2ee7 Alternative groupBy strategy. (#2998)
This patch introduces a GroupByStrategy concept and two strategies: "v1"
is the current groupBy strategy and "v2" is a new one. It also introduces
a merge buffers concept in DruidProcessingModule, to try to better
manage memory used for merging.

Both of these are described in more detail in #2987.

There are two goals of this patch:

1. Make it possible for historical/realtime nodes to return larger groupBy
   result sets, faster, with better memory management.
2. Make it possible for brokers to merge streams when there are no order-by
   columns, avoiding materialization.

This patch does not do anything to help with memory management on the broker
when there are order-by columns or when there are nested queries. That could
potentially be done in a future patch.

Gian Merlino 1853f36e9f More consistent empty-set filtering behavior on multi-value columns.
The behavior is now that filters on "null" will match rows with no
values. The behavior in the past was inconsistent; sometimes these
filters would match and sometimes they wouldn't.

Adds tests for this behavior to SelectorFilterTest and
BoundFilterTest, for query-level filters and filtered aggregates.

Fixes #2750.
