Gian Merlino f0b7c272b9 Broker: Start up DruidSchema immediately if there are no segments. (#6765)

Broker: Await initialization before finishing startup. (#6742)
* Broker: Await initialization before finishing startup.

In particular, hold off on announcing the service and starting the
HTTP server until the server view and SQL metadata cache are finished
initializing. This closes a window of time where a Broker could return
partial results shortly after startup.

As part of this, some simplification of server-lifecycle service
announcements. This helps ensure that the two different kinds of
announcements we do (legacy and new-style) stay in sync.

* Remove unused imports.

* Fix NPE in ServerRunnable.

* SystemSchema: Fix data types for various fields.

- segments: start, end, partition_num

else queries may generate ClassCastExceptions.

Also adjusted some of the code for generating values to be more
robust in the face of nulls or malformed strings.

function is 1-indexed.

Renamed 'Generic Column' -> 'Numeric Column'; Fixed a few resource leaks in processing; misc refinements (#5957)
This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.

Some of the changes:
 - Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
 - Generified `ComplexMetricExtractor`

Gian Merlino 3548396a45 SQL: Update to Calcite 1.17.0. (#6404)
* SQL: Update to Calcite 1.17.0.

Other than keeping things fresh, another motivation is that
this fixes CALCITE-1436 (AggregateNode NPE for aggregators other
than SUM/COUNT), which affects aggregate functions on our system
tables.

Also sets shouldConvertRaggedUnionTypesToVarying = true, a new
type system parameter that prefers VARCHAR over CHAR. This is
better for Druid, because we don't really have support for a
true CHAR type.

* Remove unused import.

SQL: Fix too-strict check in SortProject. (#6403)
The "Duplicate field name" check on inputRowSignature is too strict:
it is actually fine for a row signature to have the same field name
twice. It happens when the same expression is selected twice, and
both selections map to the same Druid object (dimension, aggregator,
etc).

I did not succeed in writing a test that triggers this, but I did see
it occur in production for a complex query with hundreds of aggregators.

Gian Merlino 80224df36a SQL: Fix post-aggregator naming logic for sort-project. (#6250)
The old code assumes that post-aggregator prefixes are one character
long followed by numbers. This isn't always true (we may pad with
underscores to avoid conflicts). Instead, the new code uses a different
base prefix for sort-project postaggregators ("s" instead of "p") and
uses the usual Calcites.findUnusedPrefix function to avoid conflicts.

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 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.

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

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.

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

* CR comments.

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.

* Code style

* Remove unused imports.

* Fix tests.

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.

* Fix DruidSchema, and unused imports.

* Remove unused import.

* Fix SqlBenchmark.

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.

* SQL: More forgiving Avatica server.

- Automatically close statements that are fully iterated or that have

  open statement limits.
- Empower client auto-reconnects by throwing NoSuchConnectionException

- 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.

* 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.
