> GraphComputer has vertexFilter and edgeFilter, but not yet a filter for
> vertex properties. Many vertex programs don't need many if not all vertex
> properties. PageRank, for example, does not need any vertex properties at
> all. Having a vertex property filter can greatly reduce memory/disk usage.
>
> I implemented a vertex property filter and will submit a PR soon. In my use
> case, the RDD size reduces from 2.8GB to 2.1GB by applying a vertex property
> filter. That's 25% storage saving.
