--------------------------------------

             Summary: Revisit Accumulation interface
                 Key: APEXMALHAR-2145
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2145
             Project: Apache Apex Malhar
          Issue Type: Wish
            Reporter: Vlad Rozov


Please see discussion regarding accumulation function and accumulator in https://github.com/apache/apex-malhar/pull/319.
While accumulation function should not define storage and should provide a generic way to
define how tuples are accumulated, accumulator represents actual aggregation and needs to
define the most optimal storage for a particular aggregation type.
