             Summary: Optimize Join accumulation by changing the data structure in accumulation method
                 Key: APEXMALHAR-2430
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2430
             Project: Apache Apex Malhar
          Issue Type: Improvement
            Reporter: Hitesh Kapoor
            Assignee: Hitesh Kapoor


Instead of having a list of map we can have List<MultiMap<Object, Object>> The key to multimap is a unique object generated for set of keys configured  and value of multimap can contain more than one object for the same key.
This way, while making the comparison, it becomes straightforward how to get the matching pairs.
