case class WriteFileResult ( rows: Array [ Row ] , schema: StructType ) extends Product with Serializable

Represents the results of writing data from a DataFrame to a file in a stage.

To write the data, the DataFrameWriter effectively executes the COPY INTO <location> command. WriteFileResult encapsulates the output returned by the command:

  • rows represents the rows of output from the command.
  • schema defines the schema for these rows.

For example, if the DETAILED_OUTPUT option is TRUE, each row contains a file_name , file_size , and row_count field. schema defines the names and types of these fields. If the DETAILED_OUTPUT option is not specified (meaning that the option is FALSE), each row contains a rows_unloaded , input_bytes , and output_bytes field.

rows

The output rows produced by the COPY INTO <location> command.

schema

The names and types of the fields in the output rows.
