margo

Margo: Rudimentary in-memory cache

The purpose if this project is getting hands on experience with Go.

One thing to be aware of when looking at the source code is that most of it is generated. The design package contains the DSL that describes the API. The contents of the app, client, swagger and tool folders are all completely generated by the goagen tool. The storage package contains the storage logic and is the only non-generated directory apart from the design package.

$ make
