Retry delays increase linearly (1s, 2s, 3s, 4s). Simpler but less effective for transient failures.

Constant delay between retries. Simple but may retry too quickly or slowly depending on failure type.

Frequently asked questions

What is the typical time to process messages (p50, p95, p99)?

Analyzing metrics like p50, p95, and p99 for message processing times helps identify slow operations and potential bottlenecks within your queue system.

How do I monitor the number of messages in the dead letter queue?

Regularly monitoring the number of messages accumulating in the dead letter queue is crucial; an increase signals potential issues requiring investigation and resolution.

What does it mean to measure the percentage of workers actively processing messages?

Tracking the percentage of active workers provides insights into resource utilization, allowing you to optimize the number of workers deployed for efficient queue handling.

How should I configure and monitor Queue Depth Alerts?

Queue Depth Alerts are essential; they trigger notifications when queue depth exceeds a predefined threshold, indicating potential processing lag or overload conditions.
