Hi, For smart triggers, there is a very limited use case for commitTime/transactionID. this is because you cannot ask for anything in the past, and the original belief was this could be used for reconnecting to crash recovery conditions, but even in that case, we can't guarantee the transactions would be read into the queues. After some discussions with the server team (who originally created/proposed these features) we will probably just deprecate and remove these as they are confusing and really of limited value after all. Sorry for the confusion on this. Some growing pains here as we flush out what we can and cannot achieve with the Smart Trigger technology.
