Optimizing Myntra’s Pricing System for Serving Millions of Traffic under 30ms Latency

摘要

Myntra’s pricing system is responsible for uploading various discounts for different products and serving them to multiple services. Currently, the pricing system has been serving discount information with a latency of 150ms for millions of traffic. With increasing scale and the need to disseminate discount information to several other systems, it became essential to scale the system to handle the increased load while maintaining its resilience, robustness, and fault tolerance. Several new features are being developed which require pricing information to be available in synchronous flows. To enable all these features, our pricing system needs to scale to handle 10s of millions of requests with latency as low as 30ms.
