Provides methods for writing data from a DataFrame to supported output destinations.

To use this object:

  1. Access an instance of a DataFrameWriter by calling the DataFrame.write method.
  2. Specify the save mode to use (overwrite or append) by caliing the mode method. This method returns a DataFrameWriter that is configured to save data using the specified mode. The default SaveMode is SaveMode.Append.
  3. Call a saveAs* method to save the data to the specified destination.

For example:
