QuickStart

Step 1: Set up Notebook Task

you can create a notebook task to tie quality directly into your Databricks Workflow:

  1. Add a new Task of type Notebook
  2. Select notebook source as Git provider. Git repository URL: https://github.com/databricks/expectations, Git reference: main
  3. Configure path as expectation_check_v2
  4. Select DBR 15.2+ cluster in Compute
  5. Add table_name in Parameters. Key: table_name, Value: <three_level_table_name>

Step 2: Task fails on violation

When the workflow runs, the Data Quality task will execute ANALYZE CONSTRAINTS on the selected table. If any constraints are violated, the task will fail and display debug information.
