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:
rowsrepresents the rows of output from the command.schemadefines 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
