「Building Uber’s Fulfillment Platform for Planet-Scale using Google Cloud Spanner」

Introduction: The Fulfillment Platform is a foundational Uber domain that enables the rapid scaling of new verticals. The platform handles billions of database transactions each day, ranging from user actions (e.g., a driver starting a trip) and system actions (e.g., creating an offer to match a trip with a driver) to periodic location updates (e.g., recalculating eligible products for a driver when their location changes). The platform handles millions of concurrent users and billions of trips per month across over ten thousand cities and billions of database transactions a day. In the previous article, we introduced the Fulfillment domain, highlighted challenges in the previous architecture, and outlined the new architecture. When designing the new architecture, we converged on leveraging Google’s Cloud Spanner, a NewSQL storage engine to satisfy the requirements of transactional consistency, horizontal scalability, and low operational overhead. This article describes how we leveraged Cloud Spanner for planet-scale architecture without sacrificing consistency guarantees and with low operational overhead.
