Docker Druid

What is Druid?

Druid is an open-source analytics data store designed for business intelligence (OLAP) queries on event data. Druid provides low latency (real-time) data ingestion, flexible data exploration, and fast data aggregation. Existing Druid deployments have scaled to trillions of events and petabytes of data. Druid is most commonly used to power user-facing analytic applications.

How to use?

Druid being a complex system, the best way to get up and running with a cluster is to use the docker-compose file provided.

Clone our public repository:

git clone git@github.com:cimatech/druid-container.git

and run :

docker-compose up

The compose file is going to launch :

• 1 zookeeper node
• 1 MySQL database

and the following druid services :

• 1 broker
• 1 overlord
• 1 middlemanager
• 1 historical
• 1 coordinator

The image contains the full druid distribution and use the default druid cli. If no command is provided the image will run as a broker.

If you plan to use this image on your local machine, be careful with the JVM heap spaces required by default (some services are launched with 15gb heap space).

The docker-compose file is setup to run on a macbook.
