There was a problem hiding this comment.
This fixes a flaky test when there can be duplicate chunk ids due to them overlapping 2 days and hence getting indexed in 2 tables. When chunk from each table gets deleted they get added here, hence creating a duplicate entry.

skip applying retention when data in table is still within retention …period and there are no overlapping delete requests
What this PR does / why we need it:
During each compaction, we download and iterate through all the tables and check each table for whether there are any chunks expired due to configured retention policy or a user issued delete request.
This causes the compaction to slow down and wastes the resources. This PR changes the code to check whether a table would have any expired data due to configured retention period or user issued delete request before applying retention to it. If there is no expired data then the whole table would be skipped.
