public enum ReadConcernLevel
  Member nameValueDescription
Available0 Reads available data.
Local1 Reads data committed locally.
Majority2 Reads data committed to a majority of nodes.
Linearizable3 Avoids returning data from a "stale" primary (one that has already been superseded by a new primary but doesn't know it yet). It is important to note that readConcern level linearizable does not by itself produce linearizable reads; they must be issued in conjunction with w:majority writes to the same document(s) in order to be linearizable.
Snapshot4 Snapshot read concern level.
