Description

SQLFederationStateStore uses HikariCP, which is a very efficient thread pool, but currently only exposes the max-connections parameter, we need more configuration to control the thread pool Added minimum-idle, pool-name, idle-timeout, max-lifetime, connection-timeout parameter configuration to allow users to better use the built-in thread pool.
