 Description   

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

Just blurbing that they can be part of a transaction and re-doing the read concern table
