Intro

Note: This article is for legacy Magic ETL. For information on Magic ETL v2, see Magic ETL .
This article describes in detail all of the Edit Data tiles in Magic ETL, including the following:
  • Select and Store Columns
  • Restore Columns
Note: These tiles are available by default for users on the Domo Consumption agreement.For non-consumption users, they are available on demand and paid . To enable these tiles, contact your Domo account team. You may need to complete training before using the tiles.
Learn how to create a Magic ETL DataFlow.

Prerequisites

The Performance tiles are intended for use with either the Python or R Scripting tiles. For more information on the scripting tiles, see Magic ETL Tiles: Scripting.

Select and Store Columns Tile

The Select and Store Columns tile allows you to store/remove columns that are not used as part of the script inside of a Python or R Scripting tile. Storing columns not applicable to the Scripting tiles transformations prior to the Scripting tile reduces the amount of data being loaded. Following this process will generally decrease the runtime of your Scripting tile as the tile is now only loading the necessary columns for its transformation.

Follow these steps to configure the Select and Store Columns tile:
  1. Click the Select and Store Columns tile in the canvas.
  2. (Optional) Rename the tile by clicking , then entering the name you want.
  3. Select the columns you want to use in the subsequent Python or R Scripting tile.
  4. (Optional) To verify all desired columns have been selected, hide all non-selected columns in the list by clicking .
  5. Name the column that you will use to restore the columns to the DataFlow.
Important: Do not modify the column you named in this step in any other tile in the DataFlow or the Restore Columns tile will not work as expected.

​
Restore Columns Tile

The Restore Columns tile allows you to restore/add the stored columns back into your DataFlow after the script in your Python or R Scripting tile has been processed.
