Methods

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

Applies a declarative mapping to a specified DynamicFrame.

  • frame – The DynamicFrame in which to apply the mapping (required).

  • mappings – A list of mapping tuples, each consisting of: (source column, source type, target column, target type). 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).
