MongoDB\Driver\Session::advanceClusterTime — Advances the cluster time for this session
Description
final public MongoDB\Driver\Session::advanceClusterTime
( array|object $clusterTime
) : void
Advances the cluster time for this session. If the cluster time is less than or equal to the session's current cluster time, this function is a no-op.
By using this method in conjunction with MongoDB\Driver\Session::advanceOperationTime() to copy the cluster and operation times from another session, you can ensure that operations in this session are causally consistent with the last operation in the other session.
Parameters
clusterTime- The cluster time is a document containing a logical timestamp and server signature. Typically, this value will be obtained by calling MongoDB\Driver\Session::getClusterTime() on another session object.
Return Values
No value is returned.
Errors/Exceptions
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
