class pymongo.read_concern.ReadConcern(level=None)

Parameters:
  • 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.

    Note

    ReadConcern is immutable. Mutating the value of document does not mutate this ReadConcern.

  • level

    The read concern level.

  • ok_for_legacy

    Return True if this read concern is compatible with old wire protocol versions.
