We’ve been busy shipping some powerful updates across GX  to make data quality easier, smarter, and more actionable. From expanded coverage insights to anomaly detection and new data source support, there’s a lot to explore this month.

Here’s what’s new:

Coverage Metrics just got smarter

Last month, we introduced Coverage Metrics, a new way to instantly assess your data assets' level test of coverage. This month, we’ve taken it further.

  • Spot assets with low coverage and take action directly from the table view

  • New filtering and sorting help you zero in on what matters most

  • Quickly see which assets are missing expectations or haven’t been validated in 30+ days

It's never been easier to understand and improve your test coverage in GX Cloud.

New: Data Completeness anomaly detection 

Now, you can automatically catch unexpected drops in data completeness—no need to set thresholds manually. GX Cloud users can detect completeness anomalies with just one click.

GX Cloud uses historical patterns to detect sudden changes in missing values, allowing you to catch issues before they cause downstream trouble.
