Queue

noun · also: webhook, retry, exponential-backoff

What is queue?

A queue is a buffer that holds messages or jobs until they can be processed — the backbone of resilient async systems.

Definition

Full definition of queue

When an event fires faster than you can process it, you put the work on a queue. Workers pull from the queue at their own pace. If a worker crashes, the message stays on the queue for retry. Tiny Command uses queues internally — when a webhook fires, the payload lands on a queue before being processed, so a momentary processing slowdown never loses an event.

In practice

Queue examples

Queue example
Webhook fires → message lands on queue → worker pulls it → processes → marks as done.

FAQ

Common questions about queue

FIFO or out-of-order?
Most queues are roughly FIFO but don't guarantee strict order. Use idempotency keys (not message order) for correctness.
What if a message keeps failing?
After N retries, it goes to a dead-letter queue for human inspection. Tiny Command surfaces these in the run-log.
