On the developer Q&A site Stackoverflow, Druid is described as "open-source infrastructure for real-time exploratory analytics on large datasets."[2] It is designed to ingest time-series data, chunking and compressing that data into column-based queryable segments.[3] Its architecture allows it to run as a cluster of specialized nodes to support a fault-tolerant architecture where data is stored redundantly and there are multiple members of each node type.[4]
History
Druid was created by real-time analytics company Metamarkets to use as a major part of its backend. The company open-sourced Druid in late 2012.[5] Since then, a number of organizations and companies, including Netflix[6], have integrated Druid into their backend technology.
