Citus (PostgreSQL Extension)

Citus is an extension for PostgreSQL, a popular open-source database system, that helps it handle large volumes of data and high workloads more efficiently. It spreads data across multiple servers (sharding), enabling faster processing and querying of big datasets. This allows organizations to scale their databases horizontally, improving performance and availability without changing their existing PostgreSQL setup. Essentially, Citus makes PostgreSQL capable of managing complex, large-scale applications, such as analytics or real-time services, by distributing tasks across multiple machines seamlessly.
