Apache Druid (incubating) is a high performance analytics data store for event-driven data.
To install the Druid Chart into your Kubernetes cluster :
helm install --namespace "druid" --name "druid" incubator/druidAfter 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"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.
This Helm automatically prefixes all names using the release name to avoid collisions.
This chart exposes 5 endpoints:
- Druid Overlord
- Druid Broker
- Druid Coordinator
- Druid Historical
- Druid Middle Manager
Druid configuration can be changed by using environment variables from Docker image.
See the Druid Docker entry point for more informations
Middle Managers and Historicals uses StatefulSet. Persistence is enabled by default.
