Hi @yli, Airbyte engineer here. Can we start by upgrading to 0.39 and above? 0.39 removes our old scheduler and introduces the Temporal based scheduler we use internally for all open source users. This should have much better concurrency compared to our old scheduler right off the bat and remove the configuration need using the env vars.
Are those metrics coming from our metrics collector app?
Curious, what is your RDS provisioned at today?
