Method Detail

getMessages

List<Message> getMessages()

commit

CompletableFuture<Void> commit()

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.

Returns:
