Question

A data engineering team maintains a Databricks Asset Bundle whose databricks.yml defines several jobs. Each job needs to reference the same notification email address and the same Unity Catalog catalog name in multiple places. The team wants to define these values in ONE location and reuse them throughout the bundle configuration, so a single edit updates every reference. Which Asset Bundle feature should they use?

Accepted Answer

Define custom variables in a top-level 'variables:' block and reference them with ${var.name} syntax throughout the configuration

Answer

Hard-code the values in each job definition and rely on find-and-replace when they change

Answer

Create a separate target for every value that needs to be reused

Answer

Store the values as Databricks secrets and interpolate them at deploy time in databricks.yml
