This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.

In this lesson

build the order event buffer; prepares MID-005-LAB1.

Draft outline details

Create an ArrayBlockingQueue<OrderEvent>(50) and a producer emitting events quickly.
Start 3 consumers on a fixed pool that "process" each event in 50 ms.
Log queue size and producer wait time; show the producer slowing down once the queue fills.
Planned mistake: swap in an unbounded LinkedBlockingQueue and watch the queue and heap grow without limit. Fix: restore a bound.
Add a poison pill per consumer for clean shutdown; verify produced equals consumed.

Apply this lesson with the module's lab, exercises and quiz.
