Citus: The Misunderstood Postgres Extension

Citus is an advanced Postgres extension that transforms Postgres into a sharded, distributed, horizontally scalable database suited for specific use cases. It excels in sharding multitenant applications and handling high data volume analytics with minimal user interaction. However, it is not ideal for scenarios with loose query controls or geographic residency requirements. Proper planning of shard keys and design considerations are crucial for success with Citus.
