Queue build-up issue on Paid plans

Hi,

I have a paid Activepieces cloud plan. I recently started using it for a very simple but bursty workload where I capture a request and then put it google drive and a database.

While it works fine normally, when I have bursty periods ( ~1-2 requests/second), I see that the queue builds up a lot. But the real issue is that, there is no guarantee or visibility on how the queue is getting picked up. Entries from today are being processed while those added 2 days ago are still queued.

I wanted to understand the following:

  • Do the queues not follow FIFO? If so, how are there some runs from 2 days ago still stuck in queued state
  • What is the worker concurrency on the cloud plan?
