Subject [jira] [Created] (S4-10) Dynamic s4 cluster management:S4 as a service
Date Thu, 13 Oct 2011 03:07:13 GMT
Dynamic s4 cluster management:S4 as a service

                 Key: S4-10
             Project: Apache S4
          Issue Type: New Feature
            Reporter: kishore gopalakrishna

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
