Subject [jira] [Commented] (S4-141) Enhance S4 with the elasticity feature
Date Sun, 08 Sep 2013 08:16:51 GMT


Kurtt.Lin commented on S4-141:

@Matthieu @Kishore thanks for your guys’ clarification and for your great jobs in S4-110.
We are on the same page now; let’s get first get one version out relying on checkpointing
for moving PEs. I've pulled S4 110 branch out and will look into the code in the next couple
of days to catch up with you guys.

Also agree with @Kishore that Sender and Receiver that should keep track of topology changes.
Not very urgent, though.

Indeed lots of refactors are required. @Kishore, please break it up into subtasks, will you?
Like you said, it’s an exciting path!
