Merge Content after route on attribute

Hi, This is my flow Split Text -> Route on Attribute -> Merge Content (Value 0) -> Merge Content (Value 1) Split Text can generate any number of files. Route on Attribute can only have two different attribute values to split (0 or 1). I only want Merge content to wait only for the flow files generated in it is route. For example if there are 5 flow files generated for Merge Content (Value 0), the merge content should wait for all the 5 files and merge it, similarly if there are 4 flow files generated for Merge Content (Value 1), the merge content should wait for all the 4 files and merge it. Can you please suggest how I can implement this, findings so far, 1. Using Defragement: Will not work since both merge contents are waiting for all the flow files (fragment.identifier). 2. Using Bin-Packing: Kind of there on this solution, by adding correlation identifier (my attribute value which has 0 or 1). However it is not waiting for all the flow files that is going in that route. Kindly let me know if you need additional details. Thank you! Yuva ... View more
