Andra Lungu updated FLINK-1758:
-------------------------------
Description:
Currently, the neighborhood methods only allow returning a single value per
vertex. In many cases, it is desirable to return several or no value per
vertex. This is the case in clustering coefficient computation, vertex-centric
jaccard, algorithms where a vertex computes a value per edge or when a vertex
computes a value only for some of its neighbors.
This issue proposes to
- change the current reduceOnEdges/reduceOnNeighbors methods to use combinable
reduce operations where possible
- provide groupReduce-versions, which will use a Collector and allow returning
none or more values per vertex.
