Apache ShardingSphere is a distributed SQL transaction & query engine for data sharding, scaling, encryption, and more - on any database. Our community's guiding development concept is Database Plus for creating a complete ecosystem that allows you to transform any database into a distributed database system.
It focuses on repurposing existing databases, by placing a standardized upper layer above existing and fragmented databases, rather than creating a new database.
The goal is to provide unified database services and minimize or eliminate the challenges caused by underlying databases' fragmentation. This results in applications only needing to communicate with a single standardized service.
The concepts at the core of the project are Connect, Enhance and Pluggable.
Connect:Flexible adaptation of database protocol, SQL dialect and database storage. It can quickly connect applications and heterogeneous databases.Enhance:Capture database access entry to provide additional features transparently, such as: redirect (sharding, readwrite-splitting and shadow), transform (data encrypt and mask), authentication (security, audit and authority), governance (circuit breaker and access limitation and analyze, QoS and observability).Pluggable:Leveraging the micro kernel and 3 layers pluggable mode, features and database ecosystem can be embedded flexibly. Developers can customize their ShardingSphere just like building with LEGO blocks.
ShardingSphere became an Apache Top-Level Project on April 16, 2020.
So far, ShardingSphere has been used by over 10,000 projects on GitHub.

Apache ShardingSphere includes 2 independent products: JDBC & Proxy. They all provide functions of data scale-out, distributed transaction and distributed governance, applicable in a variety of situations such as Java isomorphism, heterogeneous language and Cloud-Native.
A lightweight Java framework providing extra services at the Java JDBC layer. With the client end connecting directly to the database, it provides services in the form of a jar and requires no extra deployment and dependence.

A transparent database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. Friendlier to DBAs, the MySQL and PostgreSQL version now provided can use any kind of terminal.

ShardingSphere-JDBC adopts a decentralized architecture, applicable to high-performance light-weight OLTP applications developed with Java. ShardingSphere-Proxy provides static entry and all languages support, suitable for OLAP application and sharding databases management and operation.
Through the mixed use of ShardingSphere-JDBC & ShardingSphere-Proxy together with a unified sharding strategy by the same registry center, the ShardingSphere ecosystem can build an application system suitable to all kinds of scenarios.
