> This mechanism is designed for uploading file in parallel and asynchronously:
> - improve the performance of uploading file to OSS server. Firstly, this mechanism splits result to multiple small blocks and upload them in parallel. Then, getting result and uploading blocks are asynchronous.
> - avoid buffering too large result into local disk. To cite an extreme example, there is a task which will output 100GB or even larger, we may need to output this 100GB to local disk and then upload it. Sometimes, it is inefficient and limited to disk space.
