   > Can you please explain the scenario where no-compression would be beneficial?
   
   This NoneCompress Compressor will improve the speed of loading data from Flink to OBS File by trade-off space and IO in some cases. 
   
   For example: when loading data from Flink to OBS, data needs to be compressed by Flink to temporary files and then decompressed by OBS. 
   After adding the NoneCompressor, users can use the NoneCompressor load data without compress first and then decompress the temporary files.
