    Permalink

    GetLastError Command.

    GetLastError Command.

    This command is used to check the status of the immediately previous operation. It is commonly used to make sure that a write request has been effectively done (so it is also known as writeConcern). This command will return only when the previous operation is complete and matches its parameters (for example, with waitForReplicatedOn set to Some(2), this command will return only when at least two replicas have also run the previous operation).

    j

    Make sure that the previous operation has been committed into the journal. Journaling must be enabled on the servers.

    w

    Specify the level of replication for a write operation. Should be a BSONString or BSONInteger. See the MongoDB documentation.

    wtimeout

    Write propagation timeout (in milliseconds). See the MongoDB documentation.

    fsync

    Make sure that the previous (write) operation has been written on the disk.
