## Entries

- [Event Ordering](https://banes-lab.com/records/architecture/event-ordering.md): A rule or precondition that a stateful consumer processes the events of one key in their sequence order.
- [Backpressure](https://banes-lab.com/records/architecture/backpressure.md): A mechanism that lets a consumer signal its capacity, so a producer slows down when the consumer falls behind.
- [Rate Limiting](https://banes-lab.com/records/architecture/rate-limiting.md): A mechanism that caps how many requests a caller can make in a time window and rejects the excess.
