What problem does it solve?

This Skill provides robust patterns for implementing advanced data quality validation in Databricks, offering detailed failure insights and flexible quarantine strategies beyond standard DLT expectations.

Core Features & Use Cases

• Enhanced Diagnostics: Captures detailed reasons for data quality failures.
• Flexible Quarantine: Allows for configurable strategies to handle invalid data (drop, mark, split).
• Use Case: Integrate DQX into your Silver layer pipeline to automatically identify and quarantine records with null critical fields or values outside acceptable ranges, providing clear reasons for each failure.

Quick Start

Apply DQX checks defined in dqx_checks.yml to your input DataFrame df and split the results into valid and invalid DataFrames.
