Rohit commented on FLINK-1536:
------------------------------
Are the Graphs Created in Gelly Mutable? I mean when you perform the mutation
does it updates the old data structure or create a new copy like GraphX. I am
new to flink so have not much understanding of the dataset API in flink. I am
asking this question here because if while implementing partitioning in Gelly
one need to modify the underlying data structure and if its immutable
repartitioning will create a new graph and hence doing multiple repartitioning
based on the evaluation of the graph with time will be a major problem.

> Key: FLINK-1536
> URL: https://issues.apache.org/jira/browse/FLINK-1536
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Reporter: Vasia Kalavri
> Priority: Minor
>
> Smart graph partitioning can significantly improve the performance and
> scalability of graph analysis applications. Depending on the computation
> pattern, a graph partitioning algorithm divides the graph into (maybe
> overlapping) subgraphs, optimizing some objective. For example, if
> communication is performed across graph edges, one might want to minimize the
> edges that cross from one partition to another.
> The problem of graph partitioning is a well studied problem and several
> algorithms have been proposed in the literature. The goal of this project
> would be to choose a few existing partitioning techniques and implement the
> corresponding graph partitioning operators for Gelly.
> Some related literature can be found [here|
