Description

DuplicateFlowFile is currently useful mostly for load testing, as it generates a fixed number of flow files as copies of the incoming flow file. However there is no way to distinguish the flow files from each other, so for non-test purposes, it would be nice to have a way to treat copies differently, either for routing purposes or to access other values, such as attributes with delimited fields, etc.

This Jira proposes to add the following improvements to DuplicateFlowFile:

• add a "copy.index" attribute to the outgoing flow files, setting the attribute to zero (0) on the original flow file, and incrementally setting it on the copies.

• Add support for Expression Language to the Number of Copies property
