> We do a getPathStatus call during file open for read. This call is primarily 
> used to fetch the file’s metadata properties before the actual read begins. 
> We are now introducing an optional, config-driven read flow that avoids the 
> getPathStatus call during open and instead derives required metadata from the 
> read response itself.
