--------------------------------------
Summary: Create a general purpose Aggregating processor
Key: NIFI-1926
URL: https://issues.apache.org/jira/browse/NIFI-1926
Project: Apache NiFi
Issue Type: New Feature
Reporter: Oleg Zhurakousky
Assignee: Oleg Zhurakousky
Based on multiple question on mailing list it appears that we need to have a
general purpose processor to aggregate data (FlowFiles or content of FlowFiles
etc). Basically provide an implementation of this
http://www.enterpriseintegrationpatterns.com/patterns/messaging/Aggregator.html
Keep in mind that while MergeContent processor could be looked at as one of the
variation of aggregation, the pattern and the problem has much more moving
parts that need to be addressed (release, correlation, and aggregation
strategies). So the new processor should be flexible enough to handle variety
of aggregation use cases.
