This document discusses migrating an e-commerce platform's online product catalog from Oracle Coherence to Cassandra. The goals of the migration were to minimize system restart time, have at least two copies of data in different data centers, and enable quick simple backups. Performance testing showed Cassandra was able to meet the requirements of thousands of transactions per second and handle a full data reload daily with millions of products and entities stored. Configurations like disk optimization, caching, and query routing improved Cassandra's performance and stability for this use case.
