SPQR is a sharding proxy for PostgreSQL that enables horizontal scalability by distributing queries across multiple PostgreSQL instances. Designed for large-scale, multi-tenant architectures, SPQR routes, rewrites, and manages SQL queries to ensure they are executed efficiently across shards. It provides a PostgreSQL-compatible interface so applications can scale transparently without code changes.

Features

  • Transparent SQL routing and rewriting for sharded databases
  • Compatible with standard PostgreSQL clients and drivers
  • Supports multi-tenant and horizontal scaling architectures
  • Query planner and executor for distributed workloads
  • Centralized proxy layer with custom sharding logic
  • Designed for minimal latency and high throughput
