Data profiling & sampling

Schema & Profiling tab with data profiling settings

Schema & Profiling tab with data profiling settings

You can now profile and sample data directly from the Schema & Profiling tab on any source or catalog asset, giving you deeper visibility into your data before configuring validators. See Schema & Profiling Tab in our product documentation.

​
Data profiling

Run on-demand statistical analysis of your source fields to understand value distributions and data quality. Click Profile data from the Schema & Profiling tab to get inline metrics for each field. You can scope profiling runs by selecting specific fields, setting a row limit, adjusting the sampling percentage for tables, and using partition filters to target recent data. The profile results are specific to the data type of each field, for example: min and max for integers, versus cardinality for strings. See Data Profiling in our product documentation.

​
Data sampling

Preview a tabulated sample of rows from your source to inspect actual values and verify data patterns. Click Sample data to configure and load a sample with control over fields, row limits, sampling percentage, and partition filters. An auto-generated SQL query is included in the dialog, which you can edit directly for more control. See Data Sampling in our product documentation.
