Hi Everyone, Just looking to gauge some opinion on message events vs. database polling.

I am developing a high volume process that could involve either significant send and receive message events to initiate processes or could be initiated by periodic polling of a database table.

We have examples of both but looking to decide on the best way forward and then also for re-design in the future of older processes.

I am keen to understand system performance perspectives mainly so any suggestions welcome!

Thanks, David.

Hi, we use a database poller that runs every 5 minutes which picks up to 50 new jobs to initiate through mni. We haven't seen any performance issues.

One thing to watch out is: AFAIK Processes started by the sub-process node are running on the SAME exec engine as the parent process. Processes started by sending a message to the start node are distributed to ALL exec engines.
