pg-sharding/spqr

---

PostgreSQL is awesome, but it's hard to manage a single database with some terabytes of data and 10⁵+ queries per second. Current sharding solutions focus on analytical and hybrid workloads (OLAP, HTAP). Moreover, most of those solutions do not provide a smooth path for monolith to sharded transitions, which is why Yandex Cloud's Data Platform team developed SPQR.

SPQR is a production-ready system for horizontal scaling of PostgreSQL via sharding. We appreciate any kind of feedback and contribution to the project.
