The work queue (task queue) pattern distributes time-consuming tasks among multiple workers. One producer sends tasks to a queue, and multiple consumers process them. Characteristics:
Round-robin distribution by default
Each message processed by exactly one worker
Enables horizontal scaling Use cases:
Image processing
Email sending
Report generation
Data processing pipelines
# Producer
for task in tasks:
queue.put(task)
# Multiple consumers
def worker():
while True:
task = queue.get()
process_task(task)
queue.task_done()
