  2. The oldest option related to BlockingQueue and Producer-Consumer is always the right production choice regardless of context.
  3. It provides stronger workflow coordination than a plain queue because it can block instead of forcing busy polling.
  4. Differences around BlockingQueue and Producer-Consumer are mostly cosmetic, so correctness and maintainability do not change.
