Talk abstract: Users are demanding access to large, multi-petabyte, multi-dimension, real-time datasets to answer business critical questions. Providing a self-service interface that meets the performance expectations of these users can be challenging. Enter Apache Druid: an open source analytics database powering real-time, ad hoc, lightning fast analytics. It is used for clickstream analytics, network telemetry, fraud detection, application monitoring and so much more by companies like Apple, Netflix, Twitter, and AirBnb. Druid can ingest millions of records per second and deliver sub-second response times on OLAP-style slice and dice queries. In this talk, we will start with an overview of Apache Druid followed by a look at several examples of how Druid is being used in the real-world. We'll finish up with Q&A and some virtual networking. Speaker Bio: Mike McLaughlin is a senior field engineer at Imply. He helps customers run and optimize Apache Druid in production. He has 20 years experience developing, architecting, and deploying software.
