Hi [~hsaginor@gmail.com],

I think you are essentially talking about UC1 in https://wiki.apache.org/jackrabbit/JCR%20Binary%20Usecase.

> To get file access applications normally write binaries to temp files. It would be nice
if an API existed to get file access directly from OAK. This might also meet some use cases
documented at [https://wiki.apache.org/jackrabbit/JCR%20Binary%20Usecase]
> Suggested API and implementation can be found here [1]. Also, see attached diagram [2].
> I can create a patch if I can get some feedback. Note that suggested API makes it explicit
that a temp file is created. I am not sure if direct access to files in datasore would be
safe. But I am open to suggestions.
