Nifi : Implementing the equivalent of the Aggregator EIP in Nifi

[#1]

Hi,

I'm very experienced with Apache Camel and EIP and am struggling to understand how to implement equivalents in Nifi. I understand that Nifi uses a different paradigm (flow based programming) but I don't think what I'm trying to do is unreasonable.

The screenshot is a quick mock-up of what I'm trying to achieve but I don't understand enough about Nifi to know how to implement this pattern correctly. Basically the contents of each file will be sent to many rest services and I want to aggregate the responses into a single document which will stored in elasticsearch.

Happy to be educated on how best to achieve this with Nifi but with Camel this would be straightforward.

Many thanks
