Sharding-Sphere is an open source distributed database middleware solution suite, which consists of Sharding-JDBC, Sharding-Proxy and Sharding-Sidecar(Planning). These three sub-projects are suitable for various scenarios and provide consistent functions including data sharding, distributed transaction and database orchestration.
As a Relational Database Middleware, rather than implementing a new database, Sharding-Sphere is aimed at making the most of original capacities of database (like compute and storage) and making it simpler and more efficient on distribute environment.
