> The file deletion of the gc candidates is part of the index transaction, so
> partial deletion can occur but the index does not get updated.
> For gc, the index updates need to complete to remove references to the data
> files first. Only after a successful update to the index should the removal
> proceed. If the removal fails, on restart the orphaned data files will get gc
> ed.
