import ( "database/sql" "net" "time" ) func connectToDatabase() (*sql.DB, error) { dialer := &net.Dialer{ Timeout: 5 * time.Second, // set timeout to 5 seconds } db, err := sql.Open("mysql", "user:password@tcp(address:port)/database") if err != nil { return nil, err } db.SetConnMaxLifetime(1 * time.Minute) db.SetMaxOpenConns(10) db.SetMaxIdleConns(5) db.SetConnMaxIdleTime(30 * time.Second) return db, nil }In the above code, we are setting a timeout of 5 seconds for connecting to the database using `net.Dialer`. We are also setting other parameters such as `SetConnMaxLifetime`, `SetMaxOpenConns`, etc. for the database connection. The package library for this feature is `net` which is a part of the Go standard library.
