     · Setting a high number of idle connections with db.SetMaxIdleConns(N) can reduce this churn, and help keep connections around for reuse. Keeping a connection idle for a long time can cause problems (like in this issue with MySQL on Microsoft Azure). Try db.SetMaxIdleConns(0) if you get connection timeouts because a connection is idle for too long.
