I`m in the development stage of an app and I don't make many server\cloud sql calls but for some reason I have an average of 400 usage hours a month.
When I look at the cloud sql active connections dashboard I see there is always at least one active connection but in the read\write operations it's usually on 0 besides the occasional small bumps.
I create a new connection each time I make a request to the server\cloud sql and close the connection each time when I return the response.
the connection code is(I followed the guestbook tutorial\example)
Class.forName("com.mysql.jdbc.GoogleDriver");
this.dbUrl = "jdbc:google:mysql://trivia9991:triviadb?user=root";
this.dbConn = DriverManager.getConnection(dbUrl);
the closing connection code is
this.dbConn.close();
How can this keep a connection open at all time?
