-------------------------------------
Glad to see this feature to be available for the community! We tested this
patch in our use case (local-disk-IO-bound), and gain 10x~ performance boost by
using the heap buffer.
> AliyunOSS: AliyunOSSBlockOutputStream to support heap/off-heap buffer before
> uploading data to OSS

> Recently, our customers raise a requirement: AliyunOSSBlockOutputStream
> should support heap/off-heap buffer before uploading data to OSS.
> Currently, AliyunOSSBlockOutputStream buffers data in local directory before
> uploading to OSS, it is not efficient compared to memory.
> Changes:
> # Adds heap/off-heap buffers
> # Adds limitation of memory used, and fallback to disk
