Supavisor: Scaling Postgres to 1M Connections

Maybe I’m reading this wrong, but an additional 2ms latency on every query seems pretty unacceptable to me. Do you have any plans to mitigate this downside?
even networking alone adds about 1ms or so, and these are 2 hops each side: lb - sv - db, instead of the same instance for pgb scenario
another 1ms goes for a gain of a millions connections, multitenancy, and a lot of features that are possible to implement and are planned to implement.
i am curious what usecase do you have, that 2ms is unacceptable? in most cases it would be insignificant to network latency to the end client

2ms per query, if you need a number of queries to fulfil a request starts adding up. I think for anything approaching realtime (like games) this is quite dramatic.
supabase engineer here
would be happy to answer questions about load testing setup
here is the github repo[0] with an app that helps me launch terraforms and k6 and keep track of launches/results

this was a very fun load test to run. happy to answer any questions.
shoutout to José Valim and the Dashbit team for the help on Supavisor. elixir and erlang are amazing tools.
connection limits, even with pgbouncer, have been a big support burden for us. supavisor should let us be more liberal with connections we allot to folks.
supavisor is rolled out and available for all projects to use today. contact support[0] and we can expose the supavisor connection string in your dashboard. we'll be proactively exposing it to everyone gradually over the next ~1 month. we'll run pgbouncer and supavisor both for you for probably ~5 months before you need to switch to supavisor.
also very excited at the potential features a custom postgres proxy can unlock.
