Apache Druid

Apache Druid (incubating) is a high performance analytics data store for event-driven data.

Install Chart

To install the Druid Chart into your Kubernetes cluster :

helm install --namespace "druid" --name "druid" incubator/druid

After installation succeeds, you can get a status of Chart

helm status "druid"

If you want to delete your Chart, use this command:

helm delete  --purge "druid"

Helm ingresses

The Chart provides ingress configuration to allow customization the installation by adapting the values.yaml depending on your setup. Please read the comments in the values.yaml file for more details on how to configure your reverse proxy or load balancer.

Chart Prefix

This Helm automatically prefixes all names using the release name to avoid collisions.

URL prefix

This chart exposes 5 endpoints:

  • Druid Overlord
  • Druid Broker
  • Druid Coordinator
  • Druid Historical
  • Druid Middle Manager

Druid configuration

Druid configuration can be changed by using environment variables from Docker image.

See the Druid Docker entry point for more informations

Middle Manager and Historical Statefulset

Middle Managers and Historicals uses StatefulSet. Persistence is enabled by default.
