Fire and Forget
ELI5 — The Vibe Check
Fire and forget is sending a message or request without waiting for a response — like mailing a letter without tracking. You throw it into the void and trust it'll arrive. Great for things like sending emails, logging events, or queuing background jobs. Terrible for things like processing payments or deleting data. Know the difference.
Real Talk
Fire and forget is an asynchronous messaging pattern where the sender dispatches a message without waiting for acknowledgment or response. It's used for non-critical operations like analytics events, notification triggers, and audit logging. It offers maximum throughput but no delivery guarantee. For reliable delivery, use acknowledgment-based patterns with retry logic.
When You'll Hear This
"Analytics events are fire-and-forget — we don't wait for confirmation." / "Payment processing is NOT fire-and-forget — we need to know it succeeded."

Async
Async means 'don't wait around'. You order food at a restaurant, then chat with friends instead of standing at the kitchen window staring.
At-Least-Once Delivery
At-least-once delivery guarantees every message gets delivered... but maybe more than once. If the acknowledgment gets lost, the message gets sent again.
Event-driven
Event-driven architecture means services react to things that happen instead of constantly asking 'did anything change?
Message Queue
A Message Queue is a waiting room for tasks. Producers drop tasks in the queue, consumers pick them up and process them one at a time.
