> Issue Type: Improvement
> Components: graph

> In many Giraph applications, graphs are immutable, but edges are never
> trimmed to the proper size, after input phase. This means that on average we
> often use 1.5x memory for storing them. Considering we are often memory
> bounded, adding an option to trim the edges after the input phase will help
> reduce this excess memory usage. For mutable graphs, we can also provide an
> option for the same method to be called after each superstep.
