Photon: Fault-tolerant and scalable joining of continuous data streams
Abstract:Photon is a highly fault-tolerant, scalable, low-latency and stateful distributed system to join multiple streams of data flowing continuously. Joining these data streams is critical to extract key metrics about Google ads system used for billing and internal analysis. Photon accomplishes exactly-once semantics and can automatically withstand datacenter-level outages, providing an order of magnitude higher uptime SLA relative to a single datacenter system. Our production deployment processes over one million events per second at peak with end-to-end latency of less than 30 seconds. In this talk, we will focus on detailed architecture of Photon, including a highly scalable paxos-based storage system.
报告人：Tianhao is one of the Technical Leads in Ads Data infrastructure team at Google. He has been a major contributor to the design, implementation and launch of Photon.
