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.
The bug was caused by makeExprEvalSelector returning a null object, which
it isn't supposed to do. Fixed this by renaming ConstantColumnValueSelector
to ConstantExprEvalSelector (it was only used for ExprEval anyway) and
putting logic in that class to make sure the selectors behave as expected.
* SQL: Support more result formats, add columns header.
- Add result formats for line-based JSON and CSV.
- Add X-Druid-Sql-Columns header with a list of all columns that
the response will contain.
- Add more comprehensive documentation on what callers should expect
when making Druid SQL queries.
* Fix some tests.
* Adjust tests.
* Adjust trailer, add types header.
* Fix trailers.
* Fix all inspection errors currently reported.
TeamCity builds on master are reporting inspection errors, possibly
because there was a while where it was not running due to the Apache
migration, and there was some drift.
* Fix one more location.
* Fix tests.
* Another fix.
* Fix four bugs with numeric dimension output types.
This patch includes the following bug fixes:
- TopNColumnSelectorStrategyFactory: Cast dimension values to the output type
during dimExtractionScanAndAggregate instead of updateDimExtractionResults.
This fixes a bug where, for example, grouping on doubles-cast-to-longs would
fail to merge two doubles that should have been combined into the same long value.
- TopNQueryEngine: Use DimExtractionTopNAlgorithm when treating string columns
as numeric dimensions. This fixes a similar bug: grouping on string-cast-to-long
would fail to merge two strings that should have been combined.
- GroupByQuery: Cast numeric types to the expected output type before comparing them
in compareDimsForLimitPushDown. This fixes#6123.
- GroupByQueryQueryToolChest: Convert Jackson-deserialized dimension values into
the proper output type. This fixes an inconsistency between results that came
from cache vs. not-cache: for example, Jackson sometimes deserializes integers
as Integers and sometimes as Longs.
And the following code-cleanup changes, related to the fixes above:
- DimensionHandlerUtils: Introduce convertObjectToType, compareObjectsAsType,
and converterFromTypeToType to make it easier to handle casting operations.
- TopN in general: Rename various "dimName" variables to "dimValue" where they
actually represent dimension values. The old names were confusing.
* Remove unused imports.
* Add PostgreSQLConnectorConfig to expose SSL configuration options for the Postgres Metadata Storage module.
* Fix checkstyle violations and add license header
* Convert properties in the postgres docs to be the full property path and fix typo
* Fix grammar in sslFactory docs
* 'shutdownAllTasks' API for a dataSource

* Fix three bugs with segment publishing.
1. In AppenderatorImpl: always use a unique path if requested, even if the segment
was already pushed. This is important because if we don't do this, it causes
the issue mentioned in #6124.
2. In IndexerSQLMetadataStorageCoordinator: Fix a bug that could cause it to return
a "not published" result instead of throwing an exception, when there was one
metadata update failure, followed by some random exception. This is done by
resetting the AtomicBoolean that tracks what case we're in, each time the
callback runs.
3. In BaseAppenderatorDriver: Only kill segments if we get an affirmative false
publish result. Skip killing if we just got some exception. The reason for this
is that we want to avoid killing segments if they are in an unknown state.
Two other changes to clarify the contracts a bit and hopefully prevent future bugs:
1. Return SegmentPublishResult from TransactionalSegmentPublisher, to make it
more similar to announceHistoricalSegments.
2. Make it explicit, at multiple levels of javadocs, that a "false" publish result
must indicate that the publish _definitely_ did not happen. Unknown states must be
exceptions. This helps BaseAppenderatorDriver do the right thing.
* Remove javadoc-only import.
* Updates.
* Fix test.
* Fix tests.
