Enhancements

Possible improvements

By gradually building up our goto application, we used nearly all of Go’s essential features. While this program does what we set out to do, there are a few ways it could still be improved:

• Aesthetics: the user interface could be (much) prettier. For this, you would use Go’s template package.

• Reliability: the master/slave RPC connections could be more reliable, which means that if the client-server connection goes down; the client should attempt to re-dial. A dialer goroutine could manage this.

• Resource exhaustion: as the size of the URL database grows, memory usage might become an issue. It could be resolved by dividing (sharing) the master servers by key.

• Deletion: to support the deletion of shortened URLs, the interactions between master and slave would need to be made more complicated.
