    Exceptions are raised for network issues, and server errors; the write operation waits for the server to group commit to the journal file on disk
  • MAJORITY
    Exceptions are raised for network issues, and server errors; waits on a majority of servers for the write operation
  • NONE
    No exceptions are raised, even for network issues
  • NORMAL
    Exceptions are raised for network issues, but not server errors
  • REPLICAS_SAFE
    Exceptions are raised for network issues, and server errors; waits for at least 2 servers for the write operation
  • SAFE
    Exceptions are raised for network issues, and server errors; waits on a server for the write operation
