Redis use cases

Learn how to implement common use cases with Redis

This section provides practical examples and reference implementations for common Redis use cases.

Available use cases

• Rate limiting - Implement token bucket rate limiting with Redis
• Session storage - Store web sessions in Redis with TTL-based expiration
• Time series dashboard - Build a rolling sensor graph demo with Redis time series data
• Leaderboards - Build a ranked leaderboard with sorted sets and user metadata
• Cache-aside - Cache database reads in Redis with TTL-bounded staleness
• Job queue - Run a reliable background job queue with at-least-once delivery and visibility-timeout reclaim
• Prefetch cache - Pre-load reference data into Redis so every read is a cache hit, kept current by a CDC sync worker
• Pub/sub messaging - Broadcast real-time events to many consumers with channel and pattern subscriptions
• Streaming - Process ordered event streams with consumer groups, replay, and configurable retention
• Recommendation engine - Serve personalized recommendations under tight latency budgets by combining vector similarity with structured filters in a single Redis call
