* Improve performance of StringDimensionMergerV9 and StringDimensionMergerLegacy by avoiding primitive int boxing by using IntIterator in IndexedInts instead of Iterator<Integer>; Extract some common logic for V9 and Legacy mergers; Minor improvements to resource handling in StringDimensionMergerV9
* Don't mask index in MergeIntIterator.makeQueueElement()
* DRY conversion RoaringBitmap's IntIterator to fastutil's IntIterator
* Do implement skip(n) in IntIterators extending AbstractIntIterator because original implementation is not reliable
* Use Test(expected=Exception.class) instead of try { } catch (Exception e) { /* ignore */ }
This is useful for the insert-segment-to-db tool, which would otherwise
potentially insert a lot of overshadowed segments as "used", causing
load and drop churn in the cluster.
* support finding segments from a AWS S3 storage.
* add more Uts
* address comments and add a document for the feature.
* update docs indentation
* update docs indentation
* address comments.
1. add a Ut for json ser/deser for the config object.
2. more informant error message in a Ut.
* address comments.
1. use @Min to validate the configuration object
2. change updateDescriptor to a string as it does not take an argument otherwise
* fix a Ut failure - delete a Ut for testing default max length.
* print exception details from QueryInterruptedException
* in QueryResource.java, set thread name to include dataSource names and not whole query string e.g. from QueryDataSource
* Add support for timezone in segment granularity
* CR feedback. Handle null timezone during equals check.
* Include timezone in docs.
Add timezone for ArbitraryGranularitySpec.
- Fix GroupByRowProcessor config overrides
- Fix GroupByRowProcessor resource limit checking
- Invert subquery context overrides such that for the subquery, its own
keys override keys from the outer query, not the other way around.
The last bit is necessary for the test to work, and seems like a better
way to do it anyway.
* fix ReleaseException when the path is being written by multiple task
* Do not throw IOException if another replica wins the race for segment creation
fix if check
* handle logging comments
* fix test
* Show candidate hosts for the given query
* Added test cases & minor changes to address comments
* Changed path-param to query-pram for intervals/numCandidates
* support renaming of outputName for cached select and search queries
* rebase and resolve conflicts
* rollback CacheStrategy interface change
* updated based on review comments
In ConcurrentGrouper, when it becomes clear that disk spilling is necessary, switch
from hash-based partitioning to thread-based partitioning. This stops processing
threads from blocking each other while spilling is occurring.
