Subject [jira] [Commented] (S4-91) Runtime isolation
Date Thu, 07 Mar 2013 16:10:14 GMT


Aimee Cheng commented on S4-91:

Hi Daniel, thanks for your point out! I'll think more about how to check the data and update
the test cases. And about the remote stream, you are right, the remote stream part is missed
in the current patch and it will have problem if receive remote stream. Need change RemoteStream
to use the informations of PEs to decide which nodes need be sent.

I plan to remove the round robin from remote emitter to RemoteStream. when do round robin,
the remote events need be sent to exclusive nodes and all the other nodes by using the same
way of current code. What do you think of that?

By the way, I am updating the code to fix the problem you mentioned, and will upload in this
weekend I think.

> We would like to use runtime isolation. PEs from the same APP can split to several sub-sets
and run in different JVM processes, so that we might get some benefit from it, such as isolating
the PEs which cost a lot of resources, easier to find out the PE with problem.
