How can we know when HikariCp has fully initialized its pool?

Question

I want to start my service after HikariCP has added all connection to its pool. I am using Spring Boot.

I have a large Pool size, but while starting the application it takes a lot of time for HikariCP to add the connections and I get Connection timeouts.

Answer 1

It is undocumented (and therefore officially unsupported), but you can set the Java system property com.zaxxer.hikari.blockUntilFilled=true.
