RenameField class

Renames a node within a DynamicFrame.

Example

We recommend that you use the DynamicFrame.rename_field() method to rename a field in a DynamicFrame. To view a code example, see Example: Use rename_field to rename fields in a DynamicFrame.

Methods

__call__(frame, old_name, new_name, transformation_ctx = "", info = "", stageThreshold = 0, totalThreshold = 0)

Renames a node within a DynamicFrame.

  • frame – The DynamicFrame in which to rename a node (required).

  • old_name – The full path to the node to rename (required).

    If the old name has dots in it, RenameField will not work unless you place backticks around it (``). For example, to replace this.old.name with thisNewName, you would call RenameField as follows:

    newDyF = RenameField(oldDyF, "`this.old.name`", "thisNewName")

  • new_name – The new name, including full path (required).

  • transformation_ctx – A unique string that is used to identify state information (optional).

  • info – A string associated with errors in the transformation (optional).

  • stageThreshold – The maximum number of errors that can occur in the transformation before it errors out (optional). The default is zero.

  • totalThreshold – The maximum number of errors that can occur overall before processing errors out (optional). The default is zero.
