Companion code for the Gopher Academy blog post:

http://www.gopheracademy.com/writing-a-distributed-system-library

To run the code, simply go get it:

$ go get github.com/benbjohnson/writing-a-distributed-systems-library

And then you can run the executable:

$ writing-a-distributed-systems-library

From another terminal window, you can add values to your system using something fancy like curl:

$ curl http://localhost:8000/add?value=5
5

$ curl http://localhost:8000/add?value=10
15

$ curl http://localhost:8000/add?value=-2
13

You can stop and restart the program (from the same directory) and your data will be persisted.

Cluster configuration is not included in this simple example. For a more complete example, please check out the raftd reference implementation.
