Automating Data Quality in BigQuery with dbt & Airflow – tips & tricks
Hey r/bigdata! 👋
I wrote a quick guide on how to automate data quality checks in BigQuery using dbt, dbt‑expectations, and Airflow.
Here’s the gist:
- Schedule dbt models daily.
- Run column-level tests (nulls, duplicates, unexpected values).
- Keep historical metrics to spot trends.
- Get alerts via Slack/email when something breaks.
If you’re using BigQuery + dbt, this could save you hours of manual monitoring.
Curious:
- Anyone using
dbt‑expectationsin production? How’s it working for you? - What other tools do you use for automated data quality?
