Vasia Kalavri commented on FLINK-3965:
--------------------------------------
The functionality is much needed in my opinion. My concern is what we expose to
users and what we keep internal to Gelly. If the {{DelegatingGraphAlgorithm}}
and the {{GraphAnalytic}} are intended for users, then we should make their
functionalities and differences very clear in the docs, including examples.
Maybe that can be done as part of FLINK-4104?
> Delegating GraphAlgorithm
> -------------------------

> Key: FLINK-3965
> URL: https://issues.apache.org/jira/browse/FLINK-3965
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Fix For: 1.1.0
>
>
> Complex and related algorithms often overlap in computation of data. Two such
> examples are:
> 1) the local and global clustering coefficients each use a listing of
> triangles
> 2) the local clustering coefficient joins on vertex degree, and the
> underlying triangle listing annotates edge degree which uses vertex degree
> We can reuse and rewrite algorithm output by creating a {{ProxyObject}} as a
> delegate for method calls to the {{DataSet}} returned by the algorithm.
