Choosing datastores

Routing, a key function of Uber’s Customer Obsession platform, is a distributed, high-scale, low-latency platform that acts as the “brain” connecting a customer to the best suited human to address their concerns in the fastest and most effective way - at Uber scale. Router’s journey from using MySQL as a single data store to now a hybrid model (Redis, Elastic Search, MySQL, DocStore - internal NoSQL Db) to build an omni-channel ecosystem across multiple lines of business (Rides, Eats, Delivery, OTT etc.), globally and support complex matching at an expected QPS >1K - has been transformational.
