Reflex performance issues

[kjellvs]

Dear,

I have created an event stream to which i am pushing about 150 messages per 5 seconds.

These are messages with about 5 attributes. In reflex, I have created a couple triggers which monitors the states of these attributes for varying lengths (i.e., 5 min, 10 min and 1h). When the triggers go off, I trigger a powerautomate flow which sends a message on a teams group chat.

This was working perfectly fine yesterday (4/12), but since today (5/12, about 7am GMT+1), everythign stop working. Reflex is throttling a lot, and no more triggers are being executed or forwarded. Even configuring new triggers or updating/testing existing triggers is impossible.

Did anybody else face this issue? if so, how to proceed?

Kind regards,
Kjell

Thank you for your reply, I reduced the number of messages I sent to the event stream, now it indeed does work again. 
Please keep me posted on volume scalability improvements.
Kr, Kjell

Hello @kjellvs 

I'm afraid Data Activator currently supports up to 2 events per second per stream, and might throttle your input if it goes higher than this rate. Please see this page in our user documentation, which covers Data Activator limitations. We are working to scale up to handle higher volumes as a matter of high priority and we'll update in these forums as we do so. 

Regards

James
