Check whether higher queued epochs have been seen by the last
Ndb::pollEvents2(), or whether
a TE_CLUSTER_FAILURE event was found.
It is possible, after a cluster failure has been detected, for the
highest queued epoch returned by
pollEvents2() not to be
increasing any longer. In this case, rather than poll for more
events, you should instead consume events with
nextEvent() until it detects
a TE_CLUSTER_FAILURE is detected, then
reconnect to the cluster when it becomes available again.
This method was added in NDB 7.2.21, NDB 7.3.10, and NDB 7.4.7 (Bug #18753887).
bool isExpectingHigherQueuedEpochs ( void )
True if queued epochs were seen by the last
pollEvents2() call or, in
the event of cluster failure.
