             Summary: Allow highlevel operators to have access to 
programmatically created state.
                 Key: SAMZA-1743
                 URL: https://issues.apache.org/jira/browse/SAMZA-1743
             Project: Samza
          Issue Type: Improvement
    Affects Versions: 0.14.0
            Reporter: Peter Georgantas


The window and join highlevel operators must have state by definition. When 
using these operators, the api will programmatically create the config for that 
state. The api should allow more operators (filter, map, etc) access to the 
same programmatic state definition. Having this option would help close the gap 
between code and properties files.
