[hibernate-dev] JDBC warnings performance matter

Hi, The guys at Plumbr wrote an article about how MySQL JDBC warnings are handled by Hibernate: https://plumbr.eu/blog/io/how-we-accidentally-doubled-our-jdbc-traffic-wi... I remember seeing this issue on StackOverflow too and I was curious if you want to tweak it a little bit. I also agree that relying on the log levels to prevent fetching warnings might come as a surprise to many users and we should document this behavior. We could also have a hibernate.jdbc.log.warnings boolean property to control whether we want to log those warnings or not. This way, if users set the logger level to WARN, they will see the logs generated by the framework stack and the JDBC warnings will be logged only if this configuration property is true. What do you think? Vlad
