Hi all, I'm trying to figure out how to get my hands on a list of IDs which are determined by referring to three events. I have to not use things such as join, transaction, or sub-search due to the event limits involved. Specifically, I have: Event A which contains a req_id Event B which contains the same req_id and a correlationId Event C which does not contain a req_id but contains the correlationId from Event B and also a personId that I need The reason I need to use Event A rather than just look at Event B and Event C is because there are numerous occurrences of Event B that are unrelated, so I first have to ensure they can be associated with an Event A. TLDR! I need the list of personId values that come from Event C, but first I need to make sure they are associated with Event A and Event B — the challenge being there is no one value contained by all three.
