Prerequisites
Complete 133–137 and the Advanced Node and Database guides.
Topics
- consistency, availability, partitions, replication, and leader/follower tradeoffs;
- event-driven architecture, outbox patterns, delivery semantics, and replay;
- caching and invalidation, idempotency, deduplication, and rate limiting;
- search, notifications, realtime updates, multi-region design, and disaster recovery.
Investigation
Design an event-driven task notification system. Specify the source of truth, event schema, ordering assumptions, duplicate handling, replay behavior, user-visible status, and recovery procedure.
Interview checkpoint
Do not recite a slogan about CAP. State the failure scenario, the guarantee retained, the guarantee weakened, and the operational cost.
