Apache ShardingSphere

Collaborative Infrastructure as Design: Collaboratively manage infrastructure with your coworkers synchronously sharing the same designs.

ShardingSphere provides a distributed database solution based on the underlying database, which can scale computing and storage horizontally.
With a hybrid engine based on XA and BASE transactions, ShardingSphere provides distributed transaction capabilities on top of standalone databases, enabling data security across underlying data sources.
ShardingSphere provides flexible read/write splitting capabilities and can achieve read access load balancing based on the understanding of SQL semantics and the ability to perceive the underlying database topology.
