Hello, also few questions about retention and maintenance (non Cloud): 1) Which table in DB do you recommend to maintain, any purge plans? 2) Does any service in K8s allow to scale? I.e. we have agent, hasura, apollo, graphql, towel and ui each having single pod in k8s. What if we add 1 more graphql pod for example? 3) Can we control job run history retention period?

1) check out this post https://discourse.prefect.io/t/how-can-i-free-up-postgres-database-space/290 2) only the DB is a stateful component - check this for more info https://discourse.prefect.io/t/which-prefect-server-components-are-stateless-and-can-be-scaled-horizontally/662 3) Here is how you can solve that https://discourse.prefect.io/t/how-can-i-delete-flow-runs-older-than-30-days-using-graphql-api-to-clean-up-database-space-in-prefect-server/136
