Subject [jira] [Updated] (S4-91) Runtime isolation
Date Thu, 23 Aug 2012 11:04:42 GMT

     [ https://issues.apache.org/jira/browse/S4-91?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matthieu Morel updated S4-91:
-----------------------------


In other words, you want exclusive execution of a subset of PEs in a given partition right?

In my opinion, the cleanest way to achieve this is to extend the event dispatching mechanism.
You could restrict some partitions to only receive events from some specified streams for
instance. Then there should be a way to specify the assignation of streams/prototypes to partitions.
And a way to check that (through the S4 status command?)

> 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.
