    Description

      The following test cases are showing throughput regressions notably worse than the average regressions across other query shapes:

      • Aggregation.StringUnindexedInPredWithSimpleCollation 10.11%
      • Aggregation.UnindexedLargeInNonMatching 9.84%
      • Aggregation.UnindexedLargeInMatching 9.54%
      • Aggregation.UnindexedVeryLargeInSortedMatching 7.75%
      • Aggregation.StringUnindexedInPredWithSimpleCollation (name doesn't reflect but it does have an $in) 7.64%

       

      SERVER-80468 addressed a regression related to large $in lists. We should make sure the fix from that ticket is being used on agg path, and investigate the cause of these regressions.
