What is Redis?
Redis is an open source, in-memory data structure store that can be used as a database, cache, message broker, and streaming engine. It supports strings, hashes, lists, sets, sorted sets, and more.
Why We Use Redis
Redis delivers unmatched speed for real-time operations:
- Sub-millisecond Latency: In-memory storage for instant responses
- Data Structures: Native support for lists, sets, sorted sets, and streams
- Pub/Sub: Real-time messaging between services
- Persistence Options: RDB snapshots and AOF logs for durability
- Clustering: Horizontal scaling with automatic partitioning
Our Redis Expertise
We implement Redis across various patterns:
- Caching: Application and database query caching strategies
- Session Storage: Distributed session management for web applications
- Rate Limiting: Token bucket and sliding window implementations
- Leaderboards: Sorted sets for real-time rankings and scores
- Job Queues: Background job processing with reliability guarantees
When to Choose Redis
Redis excels for:
- Caching layers to reduce database load
- Session storage in distributed systems
- Real-time leaderboards and counters
- Pub/sub messaging between services
- Rate limiting and throttling
