Databricks Certified Data Engineer - Associate

In the classic Databricks architecture, the control plane includes the Databricks web application, which is hosted completely in the control plane. The control plane manages and orchestrates the Databricks workspace, while the data plane (also called the compute plane) includes worker nodes, driver nodes, and the Databricks Filesystem (DBFS). JDBC data sources are external data sources and not part of the Databricks architecture itself.

Key points:

• Control Plane: Manages workspace, user interfaces, job scheduling, and cluster management
• Data Plane: Contains the actual compute resources (driver and worker nodes) and storage (DBFS)
• Databricks web application: The user interface for interacting with Databricks, hosted in the control plane
• Worker node & Driver node: Part of the data plane where Spark computations run
• Databricks Filesystem (DBFS): Distributed file system in the data plane
• JDBC data source: External data source, not part of Databricks architecture
