Cart Migration from Cassandra to Mongo for an enhanced shopping performance

Cart Migration from Cassandra to Mongo for an enhanced shopping performance

摘要

Cart is a critical component in an e-commerce business. A smooth checkout process increases User’s confidence in the platform. Given the importance of a Cart in preserving the user intent to purchase we need to make sure the Cart systems are highly stable, performant, fault-tolerant & resilient to high traffic.

Myntra continues to grow at a rapid pace when it comes to its user base. The more users onboard onto the platform, the more shopping carts are created and we have more operations per Cart. Cart data is persisted in the Cassandra datastore. Cassandra was a compelling choice for Cart persistence due to its massive scalability with respect to write operations and fault tolerance capabilities. However, why this failed to be our perfect choice & our migration journey towards MongoDB is what we will be discussing in this blog post.
