September Meetup: Apache Druid and Serverless Clickhouse

Prepare to dive deep into the internals of real-time analytics and OLAP systems at our upcoming Database Internals Meetup! This session is packed with insights on the latest advancements in data processing, analytics, and cloud technologies.

🗣 Speaker 1: Hellmar Becker, Imply (Creators of Apache Druid): Apache Druid - A Fast, Distributed Real-time Analytics Database

• Apache Druid was born more than 12 years ago to address the need to query large data sets, combining real time events with historical data. In this talk, Hellmar will explain the architectural decisions behind the design of Druid and discuss how Imply has built an end to end analytics system around Druid. Hellmar will explain how Druid is deployed and utilized in the context of Imply's fully managed cloud service, Polaris, and will demonstrate how to build a real time analytics pipeline with Imply in practice.

🗣 Speaker 2: Michael Lex, ClickHouse: Serverless ClickHouse Internals: Blazing Fast, Scalable OLAP Database.

• ClickHouse is an open source column-oriented distributed OLAP database. ClickHouse Cloud is a serverless hosted offering built on top of it. This presentation goes beyond the surface-level marketing and technical jargon. How does ClickHouse work? Why is it so blazingly fast? And what the heck does "serverless" even mean? We'll explore the inner workings of ClickHouse and the challenges we faced when introducing separation of storage and compute for our Cloud - highlighting both our successes and our failures.
