Redis#

This section documents the in-memory data structure store used for caching, message brokering, and high-performance databases.

🎛 Core Concepts#

• Data Types: Usage patterns for Strings, Hashes, Lists, Sets, and Sorted Sets.
• Persistence: Trade-offs between RDB (Snapshots) and AOF (Append Only File).
• Memory Management: Eviction policies (volatile-lru, allkeys-lru) and maxmemory tuning.

🛠 Operations & HA#

• High Availability: Sentinel configuration for automatic failover and monitoring.
• Clustering: Sharding strategies and hash slot management for horizontal scaling.
• CLI: Essential commands for debugging, latency monitoring, and real-time statistics.
