Subject Odg: gateway sender queue
Date Fri, 08 Nov 2019 12:00:37 GMT
Hi all,

one more clarification regarding 3rd question:

"*   Could we add extra option in gfsh command  "start gateway sender"
     that allows to control queues reset (for instance --cleanQueues)"

This option will indicate, when gateway sender is started, should we discard/clean existing
queue, or should we use existing queue.
By default it will be to discard/clean existing queue.

Best Regards,
Mario

Hi,

thanks for answers.

Some more details regarding 1st question.

Is this behavior same (for serial and parallel gateway sender) in case queue is persistent?
Meaning, should queue (persistent) be purged if we restart gateway sender?


Thanks,
Mario

Hmm, I also think stop is supposed to clear the queue. I think if you are
seeing that it doesn't clear the queue, that might be a bug.

Persistent queues will keep all of the events when you restart.

If stop does clear the queue, would this be needed? It might still be
reasonable - I've heard folks request a way to clear running queues as well.
