The preview panel allows previewing the data (max 200 rows), sorting by column, and performing filters.

Once a Transformation has been successfully built, the data is stored in .parquet file and can be efficiently queried and previewed.

By clicking on the details button next to the column names, a statistics panel will open up giving an overview and some metadata about said column such as:

  • Distinct Count

  • Null Count

  • Min/Max values

The panel also shows a breakdown of unique values and their frequency and gives the possibility to search by value.

Custom Filter

The filter input at the top of the preview panel allows SQL-style WHERE clause to be applied.

Following is an example filter:

"Airline" = 'Air France' AND "To" = 'JFK'

Data Extract

The generated dataset can be extracted as a CSV or parquet file using the export buttons at the bottom of the table.
