A Databricks Unit (DBU) is a normalized unit of processing power on the Databricks Lakehouse Platform used for measurement and pricing purposes.

The computational power a DBU represents can vary depending on factors such as the cloud provider, instance type, and region. However, it’s intended to be a consistent measure for comparison and cost estimation across different workloads and environments.

Key Points about DBUs:

• Pricing: Databricks services are typically priced based on the number of DBUs consumed over time. This means that understanding DBUs is critical to managing your Databricks costs effectively. Workload Optimization: Understanding your workload’s DBU requirements is crucial for optimizing costs and performance on Databricks.
• Cost Estimation: Databricks provides tools and calculators to help estimate your workloads’ DBU usage and associated costs.

Example:

For instance, if a specific cluster configuration is rated at 10 DBUs per hour, and you run that cluster for 5 hours, you would consume 50 DBUs (10 DBUs/hour * 5 hours). This example illustrates how DBUs are calculated based on the duration of cluster usage.
