Valkey is a high‑performance, in‑memory key‑value datastore that can be used as a cache, primary database, or message broker. It is fully open source under a BSD‑3‑Clause license and is backed by the Linux Foundation.

Use cases

• store and retrieve session data with microsecond latency
• implement a distributed lock manager for microservices
• use as an LRU cache to accelerate database queries
• build a real‑time pub/sub messaging system
• persist short‑lived user profiles in a web application
• cache API responses for high‑traffic services

When to choose

• you need sub‑millisecond read/write latency for volatile data
• you want a drop‑in Redis compatible store with a permissive BSD license
• you require built‑in data structures like hashes, lists, and streams for complex caching patterns
• you need a self‑hosted solution that can run on Linux, macOS, Windows, or container platforms

When to avoid

• your workload requires durable, on‑disk persistence with strong ACID guarantees
• you need advanced query capabilities such as SQL or full‑text search
• you prefer a managed cloud service with automatic scaling and backups
