What it is
Redis is a blazing-fast in-memory key-value store used for caching, session storage, pub/sub, rate limiting, and queues.
The standard in-memory store for caching, queues, and real-time data.
When it fits — and when it doesn’t
A good fit for
Caching and rate limiting
Sub-ms reads relieve your primary DB
Queues and real-time features
Streams and pub/sub for events
Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Memory-bound and volatile by default
Datasets must fit in RAM; persistence needs configuration
- 02
Not a primary system-of-record
Best as a cache/auxiliary store, not source of truth
What it does well
Extremely fast
In-memory access delivers sub-millisecond latency
Versatile primitives
Strings, hashes, streams, pub/sub, sorted sets for many patterns
Ubiquitous ecosystem
Clients and managed options everywhere (incl. serverless Upstash)
