FAQs

What is a DBU?

A Databricks Unit (“DBU”) is a unit of processing capability per hour, billed on per-second usage. Databricks supports many AWS EC2 instance types. The larger the instance is, the more DBUs you will be consuming on an hourly basis. For example, 1 DBU is the equivalent of Databricks running on a c4.2xlarge machine for an hour. See the full list of supported instances and details.

I see three different prices for different types of clusters – Data Engineering Light, Data Engineering and Data Analytics. How can I pick the one that I want?

In the same workspace, you can run different workloads on different cluster types to meet the specific requirements and cost profile of your work. Databricks meters your usage of each cluster type and bills you based on the unit price of each cluster. For example, you may schedule complex jobs on a Data Engineering cluster at $0.15 per DBU, run overnight jobs on a Data Engineering Light cluster at $0.07 per DBU, and perform notebook analytics on an Data Analytics cluster at $0.40 per DBU.

There are two cluster options for production jobs – Data Engineering Light and Data Engineering. How do I decide which one to use?

Data Engineering Light is Databricks’ equivalent of open source Apache Spark. It targets simple, non-critical workloads that don’t need the performance, reliability, or autoscaling benefits provided by Databricks’ proprietary technologies. In comparison, the Data Engineering cluster provides you with all of the aforementioned benefits to boost your team productivity and reduce your total cost of ownership.

What’s the difference between production and interactive analysis workloads?

Production workloads (automated workloads) are defined as jobs that both start and terminate the clusters on which they run. For example, a workload may be triggered by the Databricks Job Scheduler which launches a new Apache Spark cluster solely for the job and automatically terminates the cluster after the job is complete.

Interactive analysis workloads are workloads that are not automated workloads, e.g., running a command within Databricks notebooks. These commands run on Apache Spark clusters that may persist until manually terminated. Multiple users can share a cluster for doing interactive analysis in a collaborative way.

Databricks Operational Security add-on package has an additional charge for DBU usage. Does it apply to all workload types?

Yes, Databricks Operational Security applies to all types of clusters offered. When you choose to deploy Databricks with Databricks Operational Security, an additional charge of $0.15 per DBU will be applied on top of the cluster price. Please contact us for details.

What does the free trial include?
