* numeric quantiles sketch aggregator
* it seems that we need to synchronize all methods, which modify the state
* Seems like a false positive with -Pstrict
* code style fix
* code style fix
* use sketches-core-0.10.3
* moved cache ids to the central place
* better class names
* support large columns
* explained autodetection, added exception
* added comments regarding sketches moving on heap
* support reindexing
* implemented suggestions from jihoonson
* style fix
* use max(k, other.k) for better accuracy
* check for NilColumnValueSelector instead of null
* throw exceptions instead of providing no-op comparators
* Make enabled final in JavaScriptConfig as it is used in equals and hashCode
* Removing the cryptic boolean condition
Replacing the cryptic boolean condition with a simple assignment.
Changing the param value to boolean from Boolean.
* SQL: Improve translation of time floor expressions.
The main change is to TimeFloorOperatorConversion.applyTimestampFloor.
- Prefer timestamp_floor expressions to timeFormat extractionFns, to
avoid turning things into strings when it isn't necessary.
- Collapse CAST(FLOOR(X TO Y) AS DATE) to FLOOR(X TO Y) if appropriate.
* Fix tests.
* Kerberos TGT will expire after some pre-determined time, this patch add relogin calls
Change-Id: I17ccb9b42aa3032de5d28c8c21e4ffbe8222b815
* exit if the first login passed
Change-Id: Ifefd5e9e0dd7d07b05cc493ab1f72415de557ec2
* Kafka Index Task that supports Incremental handoffs
- Incrementally handoff segments when they hit maxRowsPerSegment limit
- Decouple segment partitioning from Kafka partitioning, all records from consumed partitions go to a single druid segment
- Support for restoring task on middle manager restarts by check pointing end offsets for segments
* take care of review comments
* make getCurrentOffsets call async, keep track of publishing sequence, review comments
* fix setEndoffset duplicate request handling, formatting
* fix unit test
* backward compatibility
* make AppenderatorDriverMetadata backwards compatible
* add unit test
* fix deadlock between persist and push executors in AppenderatorImpl
* fix formatting
* use persist dir instead of work dir
* review comments
* fix deadlock
* actually fix deadlock
* ExpressionSelectors: Add caching selectors.
- SingleLongInputCaching selector for expressions on the __time column,
using a similar optimization to SingleScanTimeDimSelector
- SingleStringInputDimensionSelector for expressions on string columns
that return strings, using a similar optimization to ExtractionFn
based DimensionSelectors.
- SingleStringInputCaching selector for expressions on string columns
that return primitives.
Also, in the SQL planner, prefer expressions for time operations
rather than extractionFns.
* Code review comments.
i.e., aggregations like COUNT(DISTINCT CASE WHEN x THEN y END). This
patch also changes complex columns to report as nullable, which
is required for them to type-check properly when used in these kinds
of filtered aggregations.
* maxQueryTimeout property in runtime properties.
* extra line
* move withTimeoutAndMaxScatterGatherBytes method to QueryLifeCycle.
* Fix initialize method.
* remove unused import.
* doc update.
* some more details in doc about query failure..
* minor fix.
* decorating QueryRunner to set and verify context. Added by servers.
* remove whitespace.
* SQL: Improved behavior when implicitly casting strings to date/time literals.
- Handle all flavors of ISO8601 and SQL literals.
- Throw errors on other literals instead of silently transforming them to 0.
* Respect timeZone when format is null.
* use ImmutableDruidDataSource for map and set
* address comments
* unused import
* allow returning only ImmutableDruidDataSource in MetadataSegmentManager
* address comments
* remove TreeSet
* revert to use TreeSet
* use default brokerServiceName when priority is not valid
* use AtomicInteger for NodesHolder.roundRobinIndex
* revert inspectionProfiles change
* adjust TieredBrokerHostSelectorTest
* combine if statements and ensure index does not become negative
* set next index with mod if overflows
* fix codestyle
* use nextIndex
* extract the while loop to a method
* Add retries for coordinator fetch and lookup start in LookupReferencesManager
* Fix LookupConfigTest
* Address comments
* Address more comments
* And address more comments
* Address comms
* Recognize 'not found' lookups in LookupReferencesManager.tryGetLookupListFromCoordinator(), by @egor-ryashin
* IT: Switch to OpenJDK8 base image.
Also split the Docker image into a base image and a child image, and
build the base image ahead of time for efficiency's sake. Also upgrade
ZK to 3.4.10.
* Additional comments about ZK upgrades.
* Add compaction task
* added doc
* use combining aggregators
* address comments
* add support for dimensionsSpec
* fix getUniqueDims and getUniqueMetics
* find unique dimensionsSpec
* fix compilation
* add unit test
* fix test
* fix test
* test for different dimension orderings and types, and doc for type and ordering
* add control for custom ordering and type
* update doc
* fix compile
* fix compile
* add segments param
* fix serde error
* fix build
