Subject [jira] [Updated] (S4-10) Dynamic s4 cluster management:S4 as a service
Date Tue, 24 Jul 2012 16:27:34 GMT

     [ https://issues.apache.org/jira/browse/S4-10?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matthieu Morel updated S4-10:
-----------------------------

    Fix Version/s:     (was: 0.5)
                   0.6

Rescheduling for a later release. 

We could even close it. As Flavio mentioned, we are probably already good with what we currently
have. Otherwise the definition of the work becomes too abstract and I feel it's too hard to
decide upon a completion state.

> One of the features that we will definitely need to make S4 as a service is being able
to do following operations without bringing down the cluster
> * Deploy/undeploy applications. High level goal is to be able to provide a uri which
will point to the application jar and deploy it to all nodes in s4 cluster.
> * Configure/add new stream into the system, this will basically contain how is the stream
partitioned. Currently each stream is partitioned based on number of nodes but this may not
always be desirable.
> * Configure/Add Processing Elements. Basically attach a PE to a stream without writing
any custom code.
> * Add query, one should be able to submit a query for common tasks like count/avg/min/max/.
This can eventually be expanded to support UDF.
> Will use this as a high level JIRA to make S4 as a service. Only features will be added
to this JIRA. For each feature we can create child JIRA
