2988 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

4 questions in Event-Driven Architecture.

  1. Event-Driven Architecture advanced

    A platform adopts event-driven architecture broadly and finds debugging and reasoning much harder. When is event-driven the wrong choice?

  2. Event-Driven Architecture advanced

    A team proposes routing every internal workflow through an event-streaming platform because it is scalable and decoupled. What questions do you ask and when is a simpler mechanism correct?

  3. Event-Driven Architecture advanced

    A topic holds 7 days of order events - about 3 TB of unique data at replication factor 3 across 24 partitions on 6 brokers - and has exactly one consumer group, which always reads within a second of the tail. At 14:00 an analytics team deploys a second consumer group configured to start from the earliest offset. What happens over the next hour?

    Review this design. Every service publishes one event type per aggregate - OrderChanged carries the whole order document plus a changeType string. Eleven consumers subscribe and each begins with a switch on changeType, ignoring types it does not care about. What would you remove, what would you change, and what would you leave alone?
