How to Install Valkey on Ubuntu 24.04

What is Valkey?

Valkey is a high-performance, in-memory key-value data store and caching engine, created as a community-driven fork of Redis following its license change. It maintains compatibility with Redis clients and APIs while remaining fully open-source under the BSD 3-Clause license. Valkey is ideal for use cases like caching, message brokering, session storage, real-time analytics, and leaderboards.

Running Valkey on Ubuntu 24.04 LTS gives you a modern, stable, and secure platform with long-term support, ensuring high availability, low-latency performance, and smooth integration with modern web stacks.

Key Features of Valkey

In-Memory Storage with Optional Persistence

Fast data access by storing keys entirely in RAM
Supports RDB snapshots and Append-Only File (AOF) for durability
Can operate as a pure cache or as a persistent NoSQL store

Rich Data Types

Strings, Hashes, Lists, Sets, Sorted Sets
Streams (for messaging and event systems)
HyperLogLogs, Bitmaps, Geospatial indexes, Pub/Sub channels

Compatible with Redis Clients

Drop-in replacement for Redis in most use cases
Works with Redis CLI and tools like redis-cli, redis-benchmark, redis-py, ioredis, etc.

Performance and Scalability

Sub-millisecond latency on common operations
Built-in replication, clustering, and high availability (Sentinel)
Support for multithreaded I/O and asynchronous commands (ongoing improvements)

Open Governance and Active Development
