Would it be a good idea to have at least a property in which I can quarkus instruct to wait with a time out. Quarkus would initialize a connection pool, and it's quite fast to boot this up; this implies there's possible multiple connections attempting to create a server - backed by filesystem locks - all at approximately the same time. What is the possible solution for resolving this issue? N. B. MySQL and MariaDB have similar issues: it's actually not easy to test them even using Docker as they will take a good time to start, and don't make it easy for developers to know if it's done starting yet. And these exceptions will stop quarkus to proceed instead of waiting for connection and trying to reconnect. The only thing about Quarkus is that it's so fast to boot that it triggers the problem with more likelyhood, but you might still have it on other platforms too, if you have bad timing luck e. g. on a fast machine with many cores.
