About

HotKV is a commercial, Redis-compatible in-memory data store for application developers and infrastructure teams. Its C++20 server executes commands across multiple CPU cores and supports RESP2/RESP3 clients, persistence, Lua scripting, clustering, key-value workloads, and vector similarity search. Additional modules provide prompt and semantic caching, RAG retrieval, LLM usage and budget tracking, and AI-agent memory; AI modules are available on HotKV Cloud’s Performance and Scale plans and by license for on-premise deployments. HotKV Cloud is a managed service with dedicated instances, while On-Premise runs on x86_64 or ARM64 Linux in a customer’s infrastructure. Redis command and behavior compatibility varies, so teams should verify the commands and features their applications require before migration.

About

​Valkey is an open source high-performance key/value datastore that supports a variety of workloads, such as caching, message queues, and can act as a primary database. It is backed by the Linux Foundation, ensuring it will remain open source forever. Valkey can run as either a standalone daemon or in a cluster, with options for replication and high availability. It natively supports a rich collection of datatypes, including strings, numbers, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, and more. You can operate on data structures in-place with an expressive collection of commands. Valkey also supports native extensibility with built-in scripting support for Lua and supports module plugins to create new commands, data types, and more. Valkey 8.1 introduces several performance improvements that reduce latency, increase throughput, and lower memory usage.
