Helios: Hyperscale Indexing for the Cloud & Edge
Summary: Helios is a hyperscale cloud/edge indexing system that feeds real-time streams into relational engines. It ingests quadrillions of events and indexes trillions of keys daily across dozens of data centers, using a simple data model and asynchronous indexing - a scalable blueprint for Microsoft-scale analytics.
