2707 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.

  5. CDC Pipeline Design intermediate

    You are sizing the Kafka topic behind a CDC pipeline. The source Postgres takes about 12 million row changes a day across 40 tables, the average row is about 1.2 KB, the connector emits before and after images plus metadata, and the platform team wants 7 days of retention so a failed consumer can be rebuilt without a new snapshot. Roughly how much broker storage, and which assumption dominates the error?
