The new backend persists all attributes in xattrs but starts offloading the grant attributes in a messagepack file when a certain size threshold has been reached. This prevents running out of space in the xattrs of node while still keeping the identity information close to the files/dirs themselves.

The new backend persists id, spaceid and mtime in xattrs while keeping additional attributes in a messagepack file. This prevents running out of space in the xattrs of node while still keeping the identity information close to the files/dirs themselves.
