MongoDB\Driver\Session::advanceClusterTime

Description

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

Void
