drive: Batch creation of directories

[AndrewThrift]

What is your current rclone version (output from rclone version)?

rclone v1.45

What problem are you are trying to solve?

I have a backup application that creates a large directory structure to store file chunks in (65535 directories at top level). When replicating this, it takes almost 9 hours to recreate the directory structure on Google Drive. It seems that rclone is performing one directory creation per API call.

How do you think rclone should be changed to solve that?

I see Google Drive supports batch operations of up to 100 operations per API call. If it is possible, it would be great if rclone could create 100 directories at a time. This would significantly drop the time needed to create large directory structures.

Hmm, interesting idea.

I don't think the go SDK supports batch operations (I'd be delighted to be proved wrong!) though :-(
