The quality of your data directly impacts the performance and trustworthiness of your AI systems and analytics. But in production, datasets drift, pipelines break silently, and anomalies slip through unnoticed. Data quality monitoring in Openlayer helps you continuously validate the health of your tables so you can detect issues before they cascade downstream.

​
How it works

1

Connect a data source

Integrating with Openlayer begins by connecting your warehouse or lakehouse (e.g., BigQuery, Databricks, Snowflake).See the Connect a data source guide for details.Connect data source
2

Select tables to monitor

After providing the necessary credentials, you can choose which tables you want to track. Openlayer automatically profiles them, capturing schema, distributions, and summary statistics.Column distribution
3

Set up tests

Add tests on top of your tables. Common examples include schema checks (unexpected columns, type mismatches) and anomaly detection (sudden spikes or drops in key metrics, missing values, etc.)Tests can run automatically at regular cadence on top of your tables.Data quality test results
4

Get notified and act

Openlayer tracks test results over time and alerts you immediately when an anomaly is detected. This way, you can respond before bad data propagates into models, dashboards, or production systems.

Next steps

By continuously monitoring table quality, Openlayer provides a feedback loop that keeps your data pipelines healthy and reliable. To try it out, check out the Connect a data source guide.
