Batch operations

[Christian Beikov]

Hello!

I am new on this list and I am not sure if this is the right place, but 
I have a question regarding "batch" like operations.

The file system implementation I use is for AWS S3 and it has to do a 
network roundtrip for every operation.
I recently have encountered the need to delete multiple files at once 
and obviously, the overhead for the roundtrips is unnecessary since the 
S3 SDK supports a batch delete operation. I then implemented a utility 
method that used the S3 SDK to delete a list of paths when the first 
path is from a S3 file system. This works for me, but I was curious if 
there is a need for such batch operations in the FileSystemProvider class.

I think it is necessary to add some more higher level methods like the 
batch operations to the FileSystemProvider and let the 
java.nio.files.Files delegate to these instead of implementing it in a 
utility class. By doing so, file system providers can do a lot of 
operations much more efficiently if they like to override it.

What do you think about that? I would very much like to help improve the 
API and see more file system provider implementations with good performance!
