The United States Postal Service (USPS) uses Apache Cassandra as a distributed database to support their tracking and sorting systems. Specifically, USPS uses Cassandra to manage their Package Platform Services (PPS), which is responsible for tracking packages as they move through the postal system. Cassandra’s distributed architecture allows USPS to handle the large volume of data generated by their tracking system, while also ensuring high availability and scalability.

By using Cassandra, USPS can store and retrieve tracking information quickly and efficiently, enabling them to provide accurate and up-to-date package tracking information to their customers. Additionally, Cassandra’s ability to handle large volumes of data makes it well-suited for USPS’s high-throughput, high-concurrency tracking system.

Overall, Apache Cassandra is an integral part of USPS’s package tracking infrastructure, helping them provide timely and accurate package tracking information to millions of customers every day.
