Single server deployment
Druid includes a launch script,
bin/start-druid that automatically sets various memory-related parameters based on available processors and memory.
It accepts optional arguments such as list of services, total memory, and a config directory to override default JVM arguments and service-specific runtime properties.
By default, the services started by
- use all processors
- can use up to 80% memory on the system
- apply the configuration files in
conf/druid/autofor all other settings.

Single server reference configurations (deprecated)
Druid includes a set of reference configurations and launch scripts for single-machine deployments.
These start scripts are deprecated in favor of the
bin/start-druid script documented above.
These configuration bundles are located in
|Configuration||Sizing||Launch command||Configuration directory|
|1 CPU, 4GiB RAM|
|4 CPU, 16GiB RAM|
|8 CPU, 64GiB RAM (~i3.2xlarge)|
|16 CPU, 128GiB RAM (~i3.4xlarge)|
|32 CPU, 256GiB RAM (~i3.8xlarge)|
|64 CPU, 512GiB RAM (~i3.16xlarge)|
micro-quickstart is sized for small machines like laptops and is intended for quick evaluation use-cases.
nano-quickstart is an even smaller configuration, targeting a machine with 1 CPU and 4GiB 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.
