In this event I will be doing a quick introduction to Command-Query Responsibility Segregation (CQRS) and Event Sourcing (ES), with a focus on what they are (and perhaps more importantly what they aren't), before opening the floor for questions.

In this second section of the meetup, people will be given the chance to ask any question they may have about CQRS and ES, like:

  1. Can\Should you use event streaming platforms to do event sourcing?
  2. Is event sourcing really complicated?
  3. Why are CQRS and ES always mentioned together?
  4. Do you need to do DDD to succeed with CQRS and ES?
  5. What are the biggest gotchas when working with CQRS and ES?

NOTE: this is a re-run of the previous event on the same subject I run last week: https://www.meetup.com/dddlondon/events/273187247/ so that people who didn't get a chance to attend (either due to time of the event or because it filled up quickly) will get a chance to ask their questions.

If you want to ask any questions, at any time during the session you can either:

  1. Write your question in the relevant section in the Miro board here: https://miro.com/app/board/o9J_kkldv6w=/
  2. Write your question on Zoom chat
