Update operations that support readConcern snapshot/txns

    • Type: Icon: Task Task
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 3.7.4
    • Affects Version/s: None
    • Component/s: manual
    • Labels:

      Since snapshot readConcern is supported within txns, Need to update operations that support txns.

      Scope of work (see below as a curated list from the readConcern snapshot ticket)

      • find
      • getMore
        • Note that it will not actually be possible to specify the readConcern level "snapshot" for getMore. Instead, it will inherit its readConcern from the originating command, as it does today.
      • parallelCollectionScan Not allowed in txns
      • aggregate (including $lookup and $geoNear)
        • but not $out. The $out stage will be prohibited for use within pipelines executed with readConcern level snapshot due to use of metadata operations.
      • distinct
      • group Since not allowed within transactions
      • geoNear (deprecated) Since not allowed in transactions
      • geoSearch
      • insert
      • update (single & multi)
      • delete (single & multi)
      • findAndModify
