Interestingly, is this a pressure test? Can you please elaborate a bit more on how the application tests it?
It was a custom coded application in Rust designed to demonstrate how this feature can reduce connections in the connection pool (deadpool of Rust with 16 connections in the pool), Because primary can commit asynchronously and release the connection back to pool and then wait for standby. I don't mind sharing the code, if that helps.
Thanks. I had a general idea via your description and I'd like to know more about the use case. Please share it if you are ok with that.
