I used JDBC as it was the most generic way I could find to capture host/port/username/password but it is NOT actually a JDBC connection. As I also noted, this does not leverage the DbApiHook or SqlAlchemy for the same reasons. @eladkal I have not unpacked how to add a new connection type, so feel free to make your own contribtion here. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
