Awesome GitHub RepositoriesDatabase Wire 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

Noria is a dynamic dataflow engine and materialized view database that transforms expensive read operations into fast keyed lookups. It operates as a stateful system that incrementally updates dependent views as underlying relational base tables change. The system can function as a MySQL protocol emulator, mimicking the binary protocol to allow applications to fetch precomputed data without changing client code. It can also be used as a Rust embedded database, integrating the server directly into a program via native bindings to perform dataflow operations without external coordination. The

YDB 是一个分布式 SQL 数据库和分析引擎，专为水平扩展和强一致性而设计。它作为一个多模型系统，通过提供可序列化 ACID 事务的分布式架构支持事务和分析工作负载。 该系统以其广泛的协议兼容性而著称，实现了用于标准 SQL 驱动程序的 PostgreSQL 有线协议和用于消息传递与流处理的 Kafka 协议。它进一步作为向量数据库，支持用于语义搜索和嵌入的向量索引以及近似最近邻搜索。 该平台使用具有行式和列式格式的混合存储模型管理数据，利用向量化查询执行进行 PB 级分析。其操作范围包括变更数据捕获流、精确一次（exactly-once）持久队列和多区域高可用性。 部署和生命周期管理通过 Kubernetes Operator 和基础设施即代码（IaC）配置提供支持。
