Setting Up Apache Druid on Kubernetes in Under 30 Minutes

I was introduced to Apache Druid a year and a half ago. During this time, I've focused on operationalizing Apache Druid on Kubernetes (K8s). I started with Helm Charts to spin up Druid clusters in this complex distributed Druid + K8s system, but I realized Helm Charts alone were not enough.

I’ve written Golang-based operators, custom controllers in Kubernetes for different use cases, and contributed various oss operators, so I was familiar with extending Kubernetes using Custom Resource Definitions (CRDs). I was thrilled to discover the Druid Operator, which had just been open-sourced in the Druid community in late 2019. The project was less than a month old when I started contributing to it.

In this blog, we will examine the use of three different data backends for event data - Apache Druid, Elasticsearch, and Rockset.

Using Event Data

Events are commonly used by systems in the following ways:
