Dynamic s4 cluster management:S4 as a service
---------------------------------------------
Key: S4-10
URL: https://issues.apache.org/jira/browse/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
