[jira] [Created] (STORM-2203) Add a getAll method to KeyValueState interface

Abhishek created STORM-2203:
-------------------------------

             Summary: Add a getAll method to KeyValueState interface
                 Key: STORM-2203
                 URL: https://issues.apache.org/jira/browse/STORM-2203
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
            Reporter: Abhishek


A getAll method which would return all the key value pairs present in the state could be really useful in Stateful bolts. Example use case - Loop over all key value pairs in state on receiving a tick tuple and store all values satisfying a given criterion to database.
I'll be happy to provide a patch if you guys think it's a good idea.
