> We are working on a specific use-case where we attempt to utilize OS buffer-cache instead
of block-cache for local reads. We have extended CacheIndexInput but found that data is duplicated
in both OS as well block-cache. Wanted to by-pass block-cache & hence the patch
> Ultimately we should also expose controls to partially add chosen blocks of a file into
block-cache
