> GraphAlgorithm to filter by maximum degree
> ------------------------------------------
>
> Key: FLINK-3925
> URL: https://issues.apache.org/jira/browse/FLINK-3925
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Minor
> Fix For: 1.1.0
>
>
> Filtering by minimum degree is K-Core which is iterative. Filtering by
> maximum degree can be performed in constant time by filtering the set of
> high-degree vertices then doing an anti-join against the original vertex set
> and two anti-joins against the original edge set.
> Two reasons to remove high-degree vertices: 1) they may simply be noise in
> the input data, and 2) speedup algorithms such as Adamic-Adar and Jaccard
> Index which run quadratic in the vertex degree.
