Valkey

Detailed Introduction

Valkey is a high-performance distributed key-value database optimized for caching and real-time workloads. It preserves the familiarity of Redis while offering native data structures, a modular plugin system, and flexible persistence and replication strategies to meet high-concurrency, low-latency requirements. The project is community-driven and hosted on GitHub with documentation and releases available on the official site.

Main Features

• Redis protocol compatibility for easy migration and ecosystem interoperability.
• Rich native data structures and extension points for custom modules and access patterns.
• Optimized execution paths and optional memory allocators to improve throughput and reduce latency.
• Support for TLS, RDMA, and cross-platform builds (Linux, macOS, *BSD) for enterprise deployments.

Use Cases

• High-concurrency caching and session stores that require minimal access latency and high throughput.
• Real-time counters, leaderboards, and ephemeral state management.
• System migrations that require Redis compatibility but demand scalable performance.
• Deployments in distributed environments that benefit from module extensions or specialized transports (e.g., RDMA).

Technical Features

• Modular architecture and plugin system for extending commands and data structures.
• Multiple build options (Makefile / CMake) and platform support to integrate into CI/CD pipelines.
• Comprehensive test and benchmark suites, with runtime tuning options for production workloads.
• Community-driven development; source hosted on GitHub (see oss_date frontmatter) with an active contributor base.

Summary

Valkey is an open-source key-value database engineered for production use, suitable for caching and real-time systems with strict latency and throughput requirements. Visit the project homepage or repository to learn more.
