Why Redis?
In modern system architecture, milliseconds are the currency of success. Redis provides the sub-millisecond latency required for high-frequency operations, real-time features, and instantaneous data access.
- ✓Memory-first architecture for absolute speed — ~100K ops/sec on a single core.
- ✓Single-threaded core for atomic operations without lock contention.
- ✓Rich data structures — not just a cache, but a remote data structure server.
- ✓Built-in Lua scripting for complex atomic transaction logic.
