ShardingSphere-Proxy review
A self-hosted proxy for routing, scaling, and high availability across four database protocols.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ShardingSphere-Proxy is a self-hosted transparent database proxy in the Apache ShardingSphere ecosystem. It provides a common proxy endpoint for applications and database tools while applying rules for sharding, query routing, read/write splitting, encryption, masking, and other distributed-database functions. It is designed for teams operating distributed or horizontally scaled database deployments, particularly those that want open-source software and control over their hosting environment.
Its main strength is the breadth of database operations handled behind one endpoint. SQL sharding and rule-based routing can distribute work across databases, while read traffic load balancing and read/write splitting help separate query paths. Backend connection pooling, high-availability discovery, and failover address connection management and continuity. The feature set also includes distributed transactions, data migration, horizontal scaling, encryption, and masking, giving teams tools for both day-to-day routing and larger topology changes.
Platform fit is broad for a self-hosted proxy: ShardingSphere-Proxy supports Linux, Windows, and macOS, with distribution options including binary packages, Docker, and Helm. Applications and database tools can connect through MySQL, PostgreSQL, openGauss, or Firebird protocol access. The trade-off is operational ownership: teams must run the proxy themselves rather than selecting a managed commercial tier. Organizations needing a focused proxy with sharding, failover, pooling, and routing should consider it; teams seeking a hosted service or a wider protocol scope should look elsewhere.
ShardingSphere-Proxy pros and cons
- Where it wins
- Combines sharding, routing, pooling, and read/write splitting
- Supports failover, load balancing, migration, and distributed transactions
- Runs on Linux, Windows, and macOS with four protocol options
- Where it doesn't
- Self-hosted deployment requires teams to operate the proxy
- No commercial paid tiers for teams seeking a managed plan
- Protocol access centers on MySQL, PostgreSQL, openGauss, and Firebird
