Single server deployment

Druid includes a set of reference configurations and launch scripts for single-machine deployments:

  • nano-quickstart
  • micro-quickstart
  • small
  • medium
  • large
  • xlarge

The micro-quickstart is sized for small machines like laptops and is intended for quick evaluation use-cases.

The nano-quickstart is an even smaller configuration, targeting a machine with 1 CPU and 4GB memory. It is meant for limited evaluations in resource constrained environments, such as small Docker containers.

The other configurations are intended for general use single-machine deployments. They are sized for hardware roughly based on Amazon’s i3 series of EC2 instances.

The startup scripts for these example configurations run a single ZK instance along with the Druid services. You can choose to deploy ZK separately as well.

The example configurations run the Druid Coordinator and Overlord together in a single process using the optional configuration druid.coordinator.asOverlord.enabled=true, described in the Coordinator configuration documentation.

While example configurations are provided for very large single machines, at higher scales we recommend running Druid in a clustered deployment, for fault-tolerance and reduced resource contention.
