I have updated my redash 5.0 to 8.0. and I faced memory issues.
What is the reason of it?
is there any way to handle it or i have to increase RAM size?

Hi, I didn’t go from 5 to 8, but I had memory issues once on 8. What I realized is that configure a high number of workers would use more memory in peak periods (multiple running queries). If you have increase the amount of worker_threads, maybe you should try reducing them and see if it’s better this way.

Also, depending on your platform… I have used zram on Linux with redash, and it absorbed memory peaks just fine.
