Sandesh updated APEXCORE-474: ----------------------------- Description: During M*1 deployment, unifier was deployed in the separate container. But there is no advantage in doing that. It is better to make the unifier THREAD_LOCAL with the downstream operator. ( https://issues.apache.org/jira/browse/APEXCORE-482 ) Note: Recently saw one Kafka ETL app, that had a total of 18 containers allocated, but out of that 5 containers were allocated for default unifiers. It also means lots of time is also spent in SerDe. Implementing this feature will improve the performance greatly. was: During M*1 deployment, unifier was deployed in the separate container.
