Subject [jira] [Commented] (TINKERPOP-1967) Add a connectedComponent() step
Date Tue, 05 Jun 2018 19:53:00 GMT

    [ https://issues.apache.org/jira/browse/TINKERPOP-1967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16502391#comment-16502391

Marc de Lignie commented on TINKERPOP-1967:

Quite busy at the moment, with other things... I put in a day or so with the Friendster graph
but was not lucky, A single 48Gb machine really could not dig it (endless spilling for lack
of memory). Hortonworks (the software on the cluster I can access) enriched their hadoop-2.7
with a hadoop-2.9 feature that made it incompatible with TinkerPop's vanilla hadoop and an
attempt to build TinkerPop with the HDP artifacts proved unsuccesful. I quit the Friendster
graph for now and will do the hopefully easier comparison between the OLTP query and the connectedComponent()
step on a few atificial graphs of increasing size. If the OLTP query still seems useful, it
will not be much work to contibrute the documentation I prepared. If not, my contribution
has not much added value. I will try to find some time.

> Given TINKERPOP-1852 we should probably just simplify and improve performance of connected
component identification. Implementing this will involved the creation of {{ConnectedComponentVertexProgram}}.
