MongoDB\Driver\Session::advanceOperationTime — Advances the operation time for this session
说明
$operationTime): voidAdvances the operation time for this session. If the operation time is less than or equal to the session's current operation time, this function is a no-op.
By using this method in conjunction with MongoDB\Driver\Session::advanceClusterTime() to copy the operation and cluster times from another session, you can ensure that operations in this session are causally consistent with the last operation in the other session.
