> [Gelly] Add a Gather-Sum-Apply iteration method
> -----------------------------------------------
>
> Key: FLINK-1514
> URL: https://issues.apache.org/jira/browse/FLINK-1514
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 0.9
> Reporter: Vasia Kalavri
> Assignee: Daniel Bali
>
> This will be a method that implements the GAS computation model, but without
> the "scatter" step. The phases can be mapped into the following steps inside
> a delta iteration:
> gather: a map on each < srcVertex, edge, trgVertex > that produces a partial
> value
> sum: a reduce that combines the partial values
> apply: join with vertex set to update the vertex values using the results of
> sum and the previous state.
