Enum FileWriterEnum 

Source 
enum FileWriterEnum {
    ParquetFileWriter(AsyncArrowWriter<Compat<FuturesAsyncWriter>>),
    FileWriter(Writer),
}
Expand description

The FileWriterEnum enum represents different types of file writers used for various sink implementations.

§Variants

  • ParquetFileWriter: Represents a Parquet file writer using the AsyncArrowWriter<W> for writing data to a Parquet file. It accepts an implementation of W: AsyncWrite + Unpin + Send as the underlying writer. In this case, the OpendalWriter serves as the underlying writer.
  • FileWriter: Represents a basic OpenDAL writer, for writing files in encodes other than parquet.

The choice of writer used during the actual writing process depends on the encode type of the sink.
