Nishant Bangarwa e0d456b1ba Uniformly set Calcite systemProperties for All Unit tests (#5451)
Fixes test failures reported in -
https://github.com/druid-io/druid/issues/4909

Issue is that If some test skips setting up Calcite system properties
with proper encoding and loads calcite classes that use that property,
All subsequent tests in the same JVM fails.

To reproduce the issue - ExpressionsTest and CalciteQueryTest from IDE
in this order.

A better fix would be to not use System Properties in calcite, This
will work for now.

All new Calcite Unit tests that are added need to inherit
CalciteTestBase.

Clint Wylie 491f8cca81 fix timewarp query results when using timezones and crossing DST transitions (#5157)
* 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

Gian Merlino 5f6bdd940b SQL: Improve translation of time floor expressions. (#5107)
* 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.

  more sense there anyway.
- Adds a SQL query test.

Fixes #4957.

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.

Gian Merlino fbd4cd633b SQL: Delay query translation until the end of planning. (#4846)
* SQL: Delay query translation until the end of planning.

This fixes a bug in which input rels to nested queries could get swapped
out by the optimizer, leading to incorrect nested query planning.

This also, I hope, makes the query translation code easier to understand. At
least for me, the PartialDruidQuery -> DruidQuery -> Query chain is easier
to understand than the previous-existing rule spaghetti.

Gian Merlino 2ce8123bdb Move scan-query from a contrib extension into core. (#4751)
* Move scan-query from a contrib extension into core.

Based on a proposal at: https://groups.google.com/d/topic/druid-development/ME_OatUDnbk/discussion

This patch also adds support for virtual columns to the Scan query,
and updates Druid SQL to use Scan instead of Select.

This patch also makes some behavioral changes to handling of the __time
column. In particular, it is now is returned as "__time" rather than
"timestamp"; it is no longer included if you do not specifically ask for
it in your "columns"; and it is returned as a long rather than a string.

Users can revert time handling to the legacy extension behavior by
setting "legacy" : true in their queries, or setting the property
druid.query.scan.legacy = true. This is meant to provide a migration
path for users that were formerly using the contrib extension.

* Adjustments from review.

* Add back Select query.

* Adjust SQL docs.

* Restore SelectQuery link.

Gian Merlino 5048ab3e96 Add metrics to the native queries underpinning SQL. (#4561)
* Add metrics to the native queries underpinning SQL.

This is done by factoring out the metrics and request log emitting
code from QueryResource into a new QueryLifecycle class. That class
is used by both QueryResource and the SQL DruidSchema and QueryMaker.

Also fixes a couple of bugs in QueryResource:

- RequestLogLine start time was set to `TimeUnit.NANOSECONDS.toMillis(startNs)`,
  which is incorrect since absolute nanos cannot be converted to millis.
- DruidMetrics.makeRequestMetrics was called with null `query` on
  unparseable queries, which led to spurious "Unable to log query"
  errors.

Partial fix for #4047.

Gian Merlino 2be7068f6e Fixes and improvements to SQL metadata caching. (#4551)
* Fixes and improvements to SQL metadata caching.

Also adds support for MultipleSpecificSegmentSpec to CachingClusteredClient.

SQL changes:
- Cache metadata on a per-segment level, in addition to per-dataSource, so
  we don't need to re-query all segments whenever a single new one appears.
  This should lower the load placed on the cluster by metadata queries.
- Fix race condition in DruidSchema that can cause us to miss metadata. It was
  possible to notice new segments, then issue a query, and have that query
  not actually hit those segments, and not notice that it didn't hit those segments.
  Then, the metadata from those segments would be ignored.
- Fix assumption in DruidSchema that all segments are immutable. Now, mutable
  segments are periodically re-queried.
- Fix inappropriate re-use of SchemaPlus. Now we create one for each planning
  cycle, rather than sharing one. It caches table objects, which we want to
  avoid, since it can cause stale metadata. We do the caching in DruidSchema
  so we don't need the SchemaPlus caching.

Server changes:
- Add a TimelineCallback to TimelineServerView, for callers that want to get updates
  when the timeline has been modified.
- Change CachingClusteredClient from a QueryRunner to a QuerySegmentWalker. This
  allows it to accept queries that are segment-descriptor-based rather than
  intervals-based. In particular it will now support MultipleSpecificSegmentSpec.

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

Gian Merlino 67b162a337 SQL: More forgiving Avatica server. (#4368)
* SQL: More forgiving Avatica server.

- Automatically close statements that are fully iterated or that have
  errors, to prevent dangling statements from causing clients to hit
  open statement limits.
- Empower client auto-reconnects by throwing NoSuchConnectionException
  when appropriate.
- Try to close empty connections when we hit the open connection limit,
  rather than failing the newly opened connection. Client
  auto-reconnections mean this shouldn't cause problems in practice.
- Improve concurrency of the server by making "connections" a
  concurrent map.
- Lower default connection timeout to PT5M from PT30M.

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.

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.
