class pymongo.read_concern.ReadConcern(level: str | None = None)#
  • level: (string) The read concern level specifies the level of isolation for read operations. For example, a read operation using a read concern level of majority will only return data that has been written to a majority of nodes. If the level is left unspecified, the server default will be used.

New in version 3.2.
