* Add aggregatorMergeStrategy property to SegmentMetadaQuery. - Adds a new property aggregatorMergeStrategy to segmentMetadata query. aggregatorMergeStrategy currently supports three types of merge strategies - the legacy strict and lenient strategies, and the new latest strategy. - The latest strategy considers the latest aggregator from the latest segment by time order when there's a conflict when merging aggregators from different segments. - Deprecate lenientAggregatorMerge property; The API validates that both the new and old properties are not set, and returns an exception. - When merging segments as part of segmentMetadata query, the segments have a more elaborate id -- <datasource>_<interval>_merged_<partition_number> format, similar to the name format that segments usually contain. Previously it was simply "merged". - Adjust unit tests to test the latest strategy, to assert the returned complete SegmentAnalysis object instead of just the aggregators for completeness. * Don't explicitly set strict strategy in tests * Apply suggestions from code review Co-authored-by: Katya Macedo <38017980+ektravel@users.noreply.github.com> * Update docs/querying/segmentmetadataquery.md * Apply suggestions from code review Co-authored-by: Katya Macedo <38017980+ektravel@users.noreply.github.com> --------- Co-authored-by: Katya Macedo <38017980+ektravel@users.noreply.github.com> |
