Hey vira28, thanks a lot for your work. This is a very promising project because other alternative like supabase/etl, Kuvasz-streamer, Sequin all have some subtle issues.

Few questions: 1) For a supabase project can we setup replication slot on replica instead of primary? https://sequinstream.com/docs/reference/databases#using-sequ...

2) For a planetscale cluster are the replication slots on primary or the follower nodes?

I'm asking because isn't setting up slots on primary riskier than setting them on replicas/followers? Because If you have them primary In case of WAL buildup your primary will go down?
