Transaction

Transaction

Transaction is implemented using MULTI, EXEC and WATCH. Using transaction directly with a Conn is not goroutine-safe, so transaction should be used with connection pool only.

tr := gore.NewTransaction(conn)
tr.Watch("a key") // Watch a key
tr.Watch("another key")
rep, _ := NewCommand("GET", "a key").Run(conn)
value, _ := rep.Int()
tr.Add(NewCommand("SET", "a key", value + 1)) // Add a command to the transaction
_, err := tr.Commit() // Commit the transaction
if err == nil {
       // Transaction OK!!!
} else if err == gore.ErrKeyChanged {
       // Watched key has been changed, transaction should be started over.
} else {
       // Other errors, transaction should be aborted
}
