Redis is an open-source, in-memory data structure server written in C that doubles as a cache, NoSQL data store, message broker, and document/vector query engine. It supports strings, lists, sets, hashes, sorted sets, JSON, time series, and provides full-text and vector search with transactions and scripting.

Use cases

• cache frequently accessed data to speed up web applications
• store user sessions in a distributed application
• build leaderboards with sorted sets
• implement rate limiting for APIs
• use as a message broker or pub/sub event bus
• run vector similarity search for AI applications
• store and query JSON documents
• track time-series metrics in real time

When to choose

• you need sub-millisecond reads and writes for real-time applications
• you want a versatile cache with multiple eviction policies and key expiration
• you need a lightweight message broker or event store
• you want combined document, full-text, and vector search in one engine
• you need high-throughput data structures like counters, queues, and leaderboards

When to avoid

• your dataset must exceed available RAM and cannot fit in memory
• you need complex multi-table relational queries and joins
• you require strict durability guarantees for every write without performance trade-offs
• you need a primary system of record with rich ACID transactional semantics
