Subject [jira] [Updated] (HAMA-767) [GSoC 2013] Vertex addition and removal
Date Fri, 19 Jul 2013 03:58:48 GMT

Anastasis Andronidis updated HAMA-767:
--------------------------------------

    Attachment: HAMA-767-v3.patch

Hello, I made some heavy modifications on doAggregationUpdates(). I created a new interface
for a new type of class (PeerAggregator) that is acting like a vertex aggregator but it has
access in GraphJobRunner. I moved every logic that applies on globalUpdateCounts inside FinishPeerAggregator.
I also used the same approach to solve the problem with vertex counting (see CountVerticesPeerAggregator).
All tests are passing, I tried to change nothing from the workflow, but unfortunately I couldn't
skip the sync for globalUpdateCounts as it was before (we are doing 2 supersteps for 1 iteration
due to aggregators). 

I still have lots to do, I just want to know if you like this approach.
