Gian Merlino 3b92220015 Reduce log spam from Avro decoders. (#4205)
These objects get constructed semi-frequently (any time a parser is
deserialized) and so info logs are spammy. They'll still appear in
task logs at least once, since they're part of the task definition and
will get logged due to that.

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.

I didn't want to make this changeset too large. Production code use was minimal
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

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 f22fb2c2cf KafkaIndexTask.
Reads a specific offset range from specific partitions, and can use dataSource metadata
transactions to guarantee exactly-once ingestion.

Each task has a finite lifecycle, so it is expected that some process will be supervising
existing tasks and creating new ones when needed.

Gian Merlino 187569e702 DataSource metadata.
Geared towards supporting transactional inserts of new segments. This involves an
interface "DataSourceMetadata" that allows combining of partially specified metadata
(useful for partitioned ingestion).

DataSource metadata is stored in a new "dataSource" table.
