Scalable Realtime Analytics using Druid

Submitted Jul 6, 2016

Traditional SaaS solutions based on hadoop datastore Hive/Hbase or classical RDBMS work well for storing data, although they are not optimized for ingesting data and making it immediately available for interactive ad-hoc low latency queries at a very high scale. Long query latencies make these solutions suboptimal choices to power interactive applications. This talk will introduce Druid as a complementing solution for scalable real-time ingestion and analytics.

Druid is an open source distributed data warehouse, designed to support OLAP-like queries and is used in production at numerous companies. It was inspired by Google’s Dremel, PowerDrill and search framework. This talk will cover druid architecture, its storage internals and the common use cases druid is a good fit for.
