GitHub - etcd-io/etcd: Distributed reliable key-value store for the most critical data of a distributed system
Note: The main branch may be in an unstable or even broken state during development. For stable versions, see releases. etcd is a distributed reliable key-value store for the most critical data of a distributed system, with a focus on being: Simple: well-defined, user-facing API (gRPC) Secure: automatic TLS with optional client cert authentication Fast: benchmarked 10,000 writes/sec Reliable: prop
GitHub - tikv/tikv: Distributed transactional key-value database, originally created to complement TiDB
TiKV is an open-source, distributed, and transactional key-value database. Unlike other traditional NoSQL systems, TiKV not only provides classical key-value APIs, but also transactional APIs with ACID compliance. Built in Rust and powered by Raft, TiKV was originally created by PingCAP to complement TiDB, a distributed HTAP database compatible with the MySQL protocol. The design of TiKV ('Ti' sta

Redis - Wikipedia
Redis (/ˈrɛdɪs/;[7][8] Remote Dictionary Server)[7] is a source-available, in-memory storage, used as a distributed, in-memory key–value database, cache and message broker, with optional durability.[9] Because it holds all data in memory and because of its design, Redis offers low-latency reads and writes, making it particularly suitable for use cases that require a cache. Redis is the most popula
