T11数据与计算科学：Druid 实时分析架构设计思路-Imply

DRUID􀀁 INTERACTIVE EXPLORATORY ANALYTICS AT SCALEOVERVIEWTHE PROBLEM‣ Arbitrary and interactive exploration of time series data  Ad-tech, system/app metrics, network/website traffic analysis‣ Multi-tenancy: lots of concurrent users‣ Scalability: 10+ TB/day, ad-hoc queries on trillions of events‣ Recency matters! Real-time analysisDEMOREQUIREMENTS‣ Scalable & highly available‣ Real-time data ingestion‣ Arbitrary data exploration with ad-hoc queries‣ Sub-second queries‣ Many concurrent readsFINDIN
