Apache ShardingSphere is an open‑source distributed database ecosystem that provides sharding, read/write splitting, encryption, and distributed transaction capabilities for existing relational databases. It acts as a middleware layer that enables horizontal scaling and advanced data management without replacing the underlying database.

Use cases

• Scale a MySQL or PostgreSQL cluster horizontally using sharding.
• Implement read/write splitting to balance load across replica databases.
• Add transparent encryption and masking to protect sensitive data in existing databases.
• Enable distributed transactions across multiple heterogeneous databases.
• Federate queries across different data sources for unified analytics.

When to choose

• You need to horizontally scale an existing relational database without migrating to a new DBMS.
• Your application requires read/write splitting for high‑throughput read workloads.
• You must enforce data encryption or masking across multiple database instances.
• You need distributed transaction support across heterogeneous databases.

When to avoid

• Your workload is simple and fits comfortably on a single database instance.
• You require a full‑featured database engine rather than a middleware layer.
• Low‑latency, single‑node performance is more critical than scalability.
