Organised by Aardling (https://aardling.eu/)

There are a set of simple rules for building event sourced Aggregates that work quite well, in most cases. However, there are a handful of common business cases that when implemented using these rules generate a tangled mess of accidental complexity. One advanced pattern that can help in these situations is the process manager. Understanding when to use them, how to build them and the trade-offs that are being made can be critical to succeeding.

This talk will give attendees an understanding of what process managers are, when to use them, how to build them and pitfalls that can cause problems. Code examples of both business and technical problems that process managers can help solve will help reinforce these ideas with stripped down implementations from systems currently in production.
