today i moved the mysql host out of k8 into a dedicated rds instance and all went well. But i started noticing that the UI in general became slow. The size of the instance is a 2 core 1gb Ram, so the smallest instance...could that be the reason of the slowness, and if so, how can i set the correct size of the instance?

We use 1 node db.t3.small for our demo.datahubproject.io and it has been working well so far. How much data have you ingested? Also can there be some network issues here?

hmm, we are at db,t4g.micro, and we are at about 2k datasets.
