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.

  3. Pipes and Filters intermediate

    A team splits a single batch job into seven stages connected by queues, so each stage can scale and be retried independently. Throughput improves. What have they given up, and when does that bill arrive?

  5. Pipes and Filters intermediate Multiple choice

    A web-indexing pipeline of the kind Baidu operates has six queue-connected stages. Roughly one document in two million makes the parse stage abort; the queue redelivers it, so that partition crash-loops and 40 minutes of documents sit behind it while the other partitions drain normally. Review the pipeline. Which single change would you make first?
