Trim support?

[Ilya Usvyatsky]

Hi folks,

Are there any plans to support something like a 'trim' command?

Here is a motivation:

I would like to be able to use /s3backer/file as a 'volume' for a file system.

Some file systems are optimized for flash-backed media, i.e. they issue a 'trim' command every time they discard a block, thus extending useful life of flash.

In case of a cloud-backed 'volume' a 'trim' command would discard a chunk that is no longer in use thus reducing the costs.

Are there any plans to support this functionality?

Thanks,

Ilya

Yes- this is already implemented.
