Awesome GitHub RepositoriesSQL Server Protocol Emulations

FerretDB is an open-source database emulator and protocol translator that mimics a MongoDB environment to support existing drivers and client tools on a relational backend. It functions as a stateless database proxy that converts binary wire protocol messages into SQL statements, allowing a relational engine to handle document-oriented requests. The project serves as a migration tool for moving applications from MongoDB to PostgreSQL without rewriting queries or changing client drivers. It achieves this by using PostgreSQL as a document store, storing and querying BSON documents through a tra

Pigsty 是一个全面的数据库基础设施编排平台，旨在自动化高可用 PostgreSQL 集群的全生命周期。它作为一个基础设施即代码（IaC）框架，通过幂等 Playbook 管理集群协调、节点配置与服务发现。通过集成分布式共识机制，该平台确保了在包括裸机与虚拟化基础设施在内的多样化环境中，自动化故障转移与一致的状态强制执行。 该平台通过一套超越标准数据库管理的强大运营能力脱颖而出。它具备内置的观测流水线，将指标、日志与追踪聚合到集中式仪表盘中，用于实时性能监控与诊断分析。此外，它还提供了一个模拟专有线路协议与 SQL 语法的迁移框架，允许将遗留企业数据库工作负载集成到现代关系型环境中。 该系统涵盖了广泛的功能面，包括带有写时复制（CoW）克隆以实现快速部署的高级存储管理，以及协调关系型引擎与缓存及对象存储服务的多数据库编排。它还整合了安全加固、自动化备份与恢复，以及通过分层代理进行的流量路由，以将客户端连接与底层集群拓扑解耦。 该项目以自包含的包镜像模型分发，能够在安全或离线环境中实现一致的部署与依赖管理。

Pigsty is a full-stack orchestration suite for deploying, monitoring, and managing high-availability PostgreSQL clusters and their supporting infrastructure. It functions as a cluster management platform and high-availability suite that automates failover, manages virtual IPs, and ensures data consistency through distributed consensus. The project distinguishes itself by providing a comprehensive database infrastructure-as-code framework and a dedicated observability stack. It incorporates a backup and recovery manager supporting point-in-time recovery via S3-compatible object storage, alongs
