a list of messages

commit

public CompletableFuture<Void> commit()

Description copied from interface: DataReceivedEvent

Commits all messages in this event at once. If there was an error while committing, there is no point of retrying committing the same messages: the whole PartitionSession should be shut down by that time. And if commit hadn't reached the server, it will resend all these messages in next PartitionSession.

Specified by:

Returns:

a CompletableFuture that will be completed when commit confirmation from server will be received
