Polling Consumer
Go check the queue yourself on a schedule — simple, controllable, slightly laggy.
Intent & Description
Real-world Use Case
Nightly report generator — polls a report-requests queue at midnight. Processes all queued requests in batch, generates reports, then goes idle. Polling fits perfectly — no need for real-time message push.

📌 TL;DR
Polling Consumer = go fetch messages on your schedule. Simple, controllable, and predictable. Trade latency for rate control. Use long-polling to cut idle resource waste.
Advantages
- Consumer controls its own consumption rate — no overload risk
- Simple to implement — just a loop with a sleep or a scheduled job
- Works with almost any storage system used as a queue
- Easy to pause, resume, and debug
Disadvantages
- Polling adds latency — messages wait until the next poll cycle
- Constant polling wastes resources when the queue is empty (use long-polling to mitigate)
- Not suitable for real-time or low-latency processing requirements
- Poll frequency tuning is a balance between latency and resource cost
