stephen mallette updated TINKERPOP-889: --------------------------------------- Fix Version/s: (was: 3.2.6) 3.2.7 > Support for partitioned vertices in GraphComputer > ------------------------------------------------- > > Key: TINKERPOP-889 > URL: https://issues.apache.org/jira/browse/TINKERPOP-889 > Project: TinkerPop > Issue Type: Improvement > Components: process > Affects Versions: 3.0.2-incubating > Reporter: Matthias Broecheler > Assignee: Marko A. Rodriguez > Labels: breaking > Fix For: 3.2.7 > > > Most natural graphs have scale free distributions which means that some > vertices in the graph have significantly more incident edges than others. On > large graphs, it is therefore not uncommon to encounter vertices whose > adjacency list is to large to be accommodated efficiently by a single machine > (due to lack of sufficient memory or because they create a hotspot). > Other graph computing frameworks have successfully addressed this "supernode > problem" by partitioning the vertex's adjacency list and processing each > subset of the adjacency list separately because merging the results (e.g. > counting edges in each subset and then adding those values to get the total > degree). TinkerPop should implement such functionality and allow partitioned > vertex adjacency lists in the input to GraphComputer. This is a critical > feature to make TP applicable to large graph computations. > This can be implemented fairly easily for local messages using the message > combiners. Global messages can be tricky however. See also TINKERPOP3-383. > This has been partially implemented in Titan's Fulgora package > (https://github.com/thinkaurelius/titan/tree/titan10/titan-core/src/main/java/com/thinkaurelius/titan/graphdb/olap). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
