When you load the Transformer view, if the data grid is enabled, you are shown column histograms that contain details about the column data. The Data Quality Bar and Histogram show a profile of the column values. For larger datasets, it may take a while to load the column histograms, which slows the loading of the Transformer view. Additionally, adding each recipe step updates the data, and consequently the column histograms are updated based on the changed values, which can also be time-consuming.

If you would like to perform some quick data transformations and decide that you do not need to view the column histograms for each update, you can enable or disable the column histograms in the Transformer page, which can improve the page performance.

This option is available in the Show/hide data grid options drop-down menu in the status bar at the bottom of the Transformer page, alongside the Edit with data grid option.

This feature can be enabled or disabled by an administrator. For more details, refer to the Workspace Settings page.

The column histograms are no longer shown. You can continue to edit the recipe.
