Citus

Citus is a database extension for PostgreSQL that helps manage large amounts of data efficiently. It distributes data across multiple servers, working together as a single system. This allows for faster processing of complex queries and better scalability, especially useful for high-traffic applications like websites or data analytics. By sharding data and balancing work across servers, Citus enables businesses to grow without hitting performance bottlenecks. Think of it as multiple interconnected storage units that collaborate seamlessly to handle more data and deliver quicker insights than a single server could manage alone.
