User use case: Mogujie

Mogujie, a prominent fashion retail platform with over 60 million users, transitioned from Cassandra to ScyllaDB for its database needs due to ScyllaDB's superior performance and efficiency. Initially, Mogujie explored columnar databases like Cassandra for real-time data storage and offline query functionality but faced challenges with Cassandra, including crashes and the need for more servers to handle high transaction rates. Discovering ScyllaDB, an open-source C++ implementation of Cassandra, Mogujie found it adept at meeting performance requirements with fewer resources, achieving 100,000 transactions per second. Despite encountering issues during deployment, such as data modeling challenges and hardware limitations, ScyllaDB's efficiency allowed Mogujie to overcome these with support from the ScyllaDB team. Adjustments such as moving to SSDs and updating the kernel version further enhanced performance. Mogujie plans to expand ScyllaDB's use, integrating it with other technologies like Spark and Kafka, demonstrating confidence in ScyllaDB's capabilities and its development team's future contributions.
