* Added org.joda.time.DateTime#(java.lang.String) to forbidden API.
* Added org.joda.time.DateTime#(java.lang.String, org.joda.time.format.DateTimeFormatter) to forbidden API.
* Add additional APIs that may create DateTime with default time zone
* Add helper function that accepts formatter to parse String.
* Add additional forbidden APIs
* Replace existing usage of forbidden APIs
* Use wrapper class to enforce Chronology on DateTimeFormatter.
* Creates constant UtcFormatter for constant ISODateTimeFormat.
* 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.
* SQL: Full TRIM support.
- Support trimming arbitrary characters
- Support BOTH, LEADING, and TRAILING
* Remove unused import.
* Fix tests, add RTRIM / LTRIM.
* Remove unused imports.
* BTRIM and docs.
* Replace for with foreach.
* BufferHashGrouperTest: Better behavior with regard to large buffers.
1) Free buffers after each test
2) Avoid mmaping past the end of a file
* Use CloserRule.
When historical caching is enabled, and a select or topN query is
issued, and then a following query with "descending": true is set, the
cached query returns the ascending result (or vice versa), often
resulting in invalid paging identifiers.
The CacheKey for these queries doesn't include the "descending" flag;
this change adds it, and fixes the problem.
* Factor QueryableIndexColumnSelectorFactory and IncrementalIndexColumnSelectorFactory out of QueryableIndexStorageAdapter and IncrementalIndexStorageAdapter; Add Offset.getBaseReadableOffset(); Remove OffsetHolder interface; Replace Cursor extends ColumnSelectorFactory with composition; Reduce indirection in ColumnValueSelectors created by QueryableIndexColumnSelectorFactory
* Don't override clone() in FilteredOffset (the prev. implementation was broken); Some warnings fixed
* Simplify Cursors in QueryableIndexStorageAdapter
* Address comments
* Remove unused and unimplemented methods from GenericColumn interface
* Comments
* Add "round" option to cardinality and hyperUnique aggregators.
Also turn it on by default in SQL, to make math on distinct counts
work more as expected.
* Fix some compile errors.
* Fix test.
* Formatting.
* Fix dimension selectors with extractionFns on missing columns.
This patch properly applies the requested extractionFn to missing columns.
It's important when the extractionFn maps null to something other than null.
* Extract helper method.
* Change contracts of VirtualColumns and VirtualColumn methods based on review comments.
* Remove unused import.
* Remove unused method.
* Adjust helper function.
* Adjustments
* Don't use limit push down with having spec
* Throw exception when forcing limit push down with having
* Tests for having and limit push down
* Fix pool sizes in unit test
* Add HistoricalCursor.getReadableOffset() to access unwrapped offset in selectors, when the 'main' offset if FilteredOffset (fixes#4628)
* Stack overflow test
* NPE thrown when empty/null is passes to TimeDimExtractionFn
* Add @Nullable where ever applicable
* Add @Nullable to SearchQuerySpec.apply()
* Remove unused
* Use Double.NEGATIVE_INFINITY and Double.POSITIVE_INFINITY instead of Double.MIN_VALUE and Double.MAX_VALUE, same for Float
* Replace usages in comments
* Fix RTree
* Remove commented code
* Add tests
* Fix GroupBy type cast error when ChainedExecutionQueryRunner merges multiple runners
* Move conversion step to separate method
* Remove unnecessary comment
* Use compute to update map
* Avoid usages of Default system Locale and printing to System.out or System.err in production code
* Fix Charset in DruidKerberosUtil
* Remove redundant string format in GenericIndexed
* Rename StringUtils.safeFormat() to unimportantSafeFormat(); add StringUtils.format() which fails as well as String.format()
* Fix testSafeFormat()
* More fixes of redundant StringUtils.format() inside ISE
* Rename unimportantSafeFormat() to nonStrictFormat()
* Add some new expression functions and macros.
See misc/math-expr.md for the list of added functions, except for
"like", which previously existed but was not documented.
* Add easymock to datasketches tests.
* Add easymock to distinctcount tests.
* Add easymock to virtual-columns tests.
* Code review comments.
* Clean up code a bit.
* Add easymock to scan-query tests.
* Rework ExprMacros that have multiple impls.
* Improve test coverage.
* Remove DruidProcessingModule, QueryableModule and QueryRunnerFactoryModule from DI for coordinator, overlord, middle-manager. Add RouterDruidProcessing not to allocate processing resources on router
* Fix examples
* Fixes
* Revert Peon configs and add comments
* Remove qualifier
* Remove ability to create segments in v8 format
* Fix IndexGeneratorJobTest
* Fix parameterized test name in IndexMergerTest
* Remove extra legacy merging stuff
* Remove legacy serializer builders
* Remove ConciseBitmapIndexMergerTest and RoaringBitmapIndexMergerTest
* ExpressionPostAggregator: Automatically finalize inputs.
Raw HyperLogLogCollectors and such aren't very useful. When writing
expressions like `x / y` users will expect `x` and `y` to be finalized.
* Fix un-merge.
* Code review comments.
* Remove unnecessary ImmutableMap.copyOf.
