[GitHub] [incubator-druid] surekhasaharan opened a new pull request #7595:
Optimize overshadowed segments computation
surekhasaharan opened a new pull request #7595: Optimize overshadowed segments computation
URL: https://github.com/apache/incubator-druid/pull/7595
Addresses part of #7571
This patch moves the computation of overshadowed segments to `SQLMetadataSegmentManager`'s poll method. The endpoint in `MetadataResource` and `DruidCoordinatorRuleRunner` use the API `MetadataSegmentManager#findOvershadowedSegments()` to get overshadowed segments without building the `VersionedIntervalTimeline` every time.
Renamed `SegmentWithOvershadowedStatus` to `DataSegmentWithOvershadowedStatus`.
This PR does not address the mutability of `DataSegment` and getting rid of interning in `MatadataSegmentView`
