Fill nulls transform - Amazon SageMaker Unified Studio

Fill nulls transform

Fill nulls allows you to fill in null value in a column with a chosen fill value. Select a column with nulls you want to fill and provide a fill value. You can use multiple fill conditions at one time. Select a subset of the data to consider by using a dropdown menu to select columns.

  1. Open the menu and then choose Fill nulls to add a new transform to your flow diagram.

  2. (Optional) Click on the rename node icon to enter a new name for the node in the flow diagram.
