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.

* 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.

* Fix docs.

will conflict and throw a slf4j multiple bindings warning.

task logs at least once, since they're part of the task definition and

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.

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.

* Create a NamespaceExtractionCacheManager separately for each test in NamespaceExtractionCacheManagersTest

* Rename CacheScheduler.NoCache.ENTRY_DISPOSED to ENTRY_CLOSED

* Reduce visibility of NamespaceExtractionCacheManager.cacheCount() and monitor() implementations, and don't run NamespaceExtractionCacheManagerExecutorsTest with off-heap cache (it didn't before)

* In NamespaceLookupExtractorFactory, use safer idiom to check if CacheState is NoCache or VersionedCache

* More logging in CacheHandler constructor and close(), VersionedCache.close()

* PR comments addressed

* Make CacheScheduler.EntryImpl AutoCloseable, avoid 'dispose' verb in comments, logging and naming in CacheScheduler in favor of 'close'

* More Javadoc comments to CacheScheduler

* Fix NPE

* Remove logging in OnHeapNamespaceExtractionCacheManager.expungeCollectedCaches()

* Make NamespaceExtractionCacheManagersTest.testRacyCreation() to have similar load to what it be before the refactoring

* Unwrap NamespaceExtractionCacheManager.scheduledExecutorService from unneeded MoreExecutors.listeningDecorator() and specify that this is ScheduledThreadPoolExecutor, which ensures happens-before between periodic runs of the tasks

* More comments on MapDbCacheDisposer.disposed

* Replace concat with Long.toString()

* Comment on why NamespaceExtractionCacheManager.scheduledExecutorService() returns ScheduledThreadPoolExecutor

* Place logging statements in VersionedCache.close() and CacheHandler.close() after actual closing logic, because logging may fail

* Make JDBCExtractionNamespaceCacheFactory and StaticMapExtractionNamespaceCacheFactory to try to close newly created VersionedCache if population has failed, as it is done already in URIExtractionNamespaceCacheFactory

* Don't close the whole CacheScheduler.Entry, if the cache update task failed

* Replace AtomicLong updateCounter and firstRunLatch with Phaser-based UpdateCounter in CacheScheduler.EntryImpl

Gian Merlino 7e80d1045a Exercise v2 engine in the groupBy aggregator and multi-value dimension tests. (#3698)
This also involved some other test changes:

- Added a factory.mergeRunners step to AggregationTestHelper's groupBy chain, since the v2
  engine does merging there.
- Changed test byteBuffer pools from on-heap to off-heap to work around
  https://github.com/DataSketches/sketches-core/pull/116 for datasketches tests.

and I switched those to non-static imports.

Roman Leventov 22b57ddd60 Make ExtractionNamespaceCacheFactory to populate cache directly instead of returning callable (#3651)
* Rename ExtractionNamespaceCacheFactory.getCachePopulator() to populateCache() and make it to populate cache itself instead of returning a Callable which populates cache, because this "callback style" is not actually needed.

ExtractionNamespaceCacheFactory isn't a "factory" so it should be renamed, but renaming right in this commit would tear the git history for files, because ExtractionNamespaceCacheFactory implementations have too many changed lines. Going to rename ExtractionNamespaceCacheFactory to something like "CachePopulator" in one of subsequent PRs.

This commit is a part of a bigger refactoring of the lookup cache subsystem.

* Remove unused line and imports

Roman Leventov 36a1543222 Lookup cache bug fixes (#3609)
* Return better lastVersion from JDBCExtractionNamespaceCacheFactory's cache populator callable

* Return the lastVersion if URI lookup last modified date is not later than the last cached, from URIExtractionNamespaceCacheFactory's cache populator callable

* Fix a race condition in NamespaceExtractionCacheManager.cancelFuture()

* Don't delete cache from NamespaceExtractionCacheManager if the ExtractionNamespaceCacheFactory returned the same version as the last; Better exception treatment in the scheduled cache updater runnable in NamespaceExtractionCacheManager (in particular, don't consume Errors); throw AssertionError in StaticMapExtractionNamespaceCacheFactory if the lastVersion != null)

* In NamespaceExtractionCacheManager, put NamespaceImplData.latestVersion update in the same synchronized() block with swapAndClearCache(id, cacheId); Turn getPostRunnable which returns a callback into a simple updateNamespace() method

* In StaticMapExtractionNamespaceCacheFactory.getCachePopulator(), check the input directly, not inside a callback

* In URIExtractionNamespaceCacheFactory, allow URI last modified time to go backwards

* Better logging in NamespaceExtractionCacheManager

* Add comment on lastVersion nullability in URIExtractionNamespaceCacheFactory
