Flink Jira Bot updated FLINK-4965:
----------------------------------
Labels: algorithm auto-deprioritized-major auto-unassigned (was:
algorithm auto-unassigned stale-major)
Priority: Minor (was: Major)
This issue was labeled "stale-major" 7 days ago and has not received any
updates so it is being deprioritized. If this ticket is actually Major, please
raise the priority and ask a committer to assign you the issue or revive the
public discussion.
> AllPairsShortestPaths
> ---------------------
>
> Key: FLINK-4965
> URL: https://issues.apache.org/jira/browse/FLINK-4965
> Project: Flink
> Issue Type: New Feature
> Components: Library / Graph Processing (Gelly)
> Affects Versions: 1.2.0
> Reporter: Greg Hogan
> Priority: Minor
> Labels: algorithm, auto-deprioritized-major, auto-unassigned
>
> Add a Gelly implementation of {{AllPairsShortestPaths}} to complement the
> existing {{SingleSourceShortestPaths}}.
> Flink algorithms excel at processing big, sparse data. APSP is big, really
> big, but not at all sparse. Considering only undirected graphs, each
> component of size {{n}} will have {{n choose 2}} shortest paths (1,000
> vertices => ~million paths, 1,000,000 vertices => ~trillion shortest paths).
> Considerations are directed vs undirected and weighted vs unweighted graphs.
> The actual shortest path (not merely the distance) is required for follow-on
> algorithms such as betweenness centrality.
