Event-driven pipelines without the operational headache

Queue-backed architectures give you resilience and scale, but they introduce complexity. Here's how we keep it sane.

Event-driven systems decouple producers from consumers and absorb traffic spikes gracefully. They also introduce ordering, retries, and idempotency concerns that can overwhelm a team.

Make every consumer idempotent

Messages will be delivered more than once. Design handlers so that processing the same event twice has no harmful effect.

Dead-letter queues are not optional

When a message cannot be processed, it needs somewhere safe to go so it does not block the pipeline or get lost.
