Modern commerce platforms are increasingly a complex interconnect of multiple distributed architecture that come together to drive experiences at scale. The ever-rising Service Level Objectives (SLOs) on response time, throughput and availability for such architectures, coupled with strong data consistency guarantees, can reach extreme levels that require ultra-fast access to data for both read and write workloads.

This talk offers a deeper perspective on how to build low-latency architectures on fast changing data by taking real-time visibility into inventory levels across our network of 2000+ stores as a case-study. Attendees will get a practical view on the architectural principles, design choices and the key lessons learnt over multiple years of building and evolving such platforms.
