UnnestFrame class

Unnests a DynamicFrame, flattens nested objects to top-level elements, and generates join keys for array objects.

Example

We recommend that you use the DynamicFrame.unnest() method to flatten nested structures in a DynamicFrame. To view a code example, see Example: Use unnest to turn nested fields into top-level fields.

Methods

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

Unnests a DynamicFrame, flattens nested objects to top-level elements, and generates join keys for array objects.

  • frame – The DynamicFrame to unnest (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.
