Systems¶
Distributed systems ideas that show up in production platforms: caching, streams, consistency, observability. Astra encodes many of these as hard SLAs (10ms reads, scheduling latency).
Subpages¶
| Page | Focus |
|---|---|
| Caching | Read paths, stampede, TTL |
| Streaming | Redis streams, consumer groups |
| Consistency | Postgres vs cache |
| Observability | Metrics, logs, traces |
