Garnet is a multi-threaded in-memory database and distributed key-value store. It functions as a high-performance remote cache store that implements the RESP wire protocol to maintain compatibility with existing Redis clients and libraries. The project is distinguished by a shared-memory architecture that enables parallel request processing across multiple cores for sub-millisecond latency. It features a tiered storage system that automatically offloads colder data from system memory to SSD or cloud storage layers, and includes a specialized vector search database for high-dimensional similar

这是一个 Kubernetes Operator，旨在通过声明式配置部署和管理生产级 PostgreSQL 数据库集群。它作为一个控制器，将数据库集群的实际状态与期望状态同步，提供了一个用于高可用性编排、自动化备份与恢复以及容器化数据库管理的系统。 该 Operator 的特色在于其全面的数据保护套件，支持时间点恢复、到云对象存储的多模式备份以及集群克隆。它使用分布式共识实现自动化故障转移，确保持续可用性，并通过集成的连接池支持复杂的流量管理。 该项目涵盖了广泛的操作功能，包括同步和异步复制、通过专用监控堆栈进行遥测收集，以及具有自动化 TLS 证书轮换的安全身份管理。它还提供了用于存储卷扩展、数据库引擎更新以及集成各种数据库扩展的工具。 该控制器使用可自定义的清单安装到集群中，以实现数据库环境的声明式编排。

sofa-jraft is a Java implementation of the Raft consensus algorithm. It serves as a distributed consensus engine and linearizable state machine designed to ensure high availability and data consistency across a cluster of nodes. The project provides a replicated key-value store and a coordination engine for managing distributed state. It distinguishes itself through support for multi-group consensus sharding to distribute traffic and a service provider interface that allows for custom log storage and entry encoding implementations. The system covers a wide range of distributed capabilities,
