I wouldn't mind knowing this information when the service starts up and detects that there is a Direct SQL compatible database, but I don't need to know about this every time.

Please lower to debug level logging and parameterize with SLF4J. Direct SQL is a performance thing and not something I care about during the normal course of operation (unless there is an error which would presumably be covered by an error logging message).
