Ethan Rose commented on HDDS-6441:
----------------------------------
For the space issue, it looks like uncommitted multi part upload parts will
remain in the OM open key table unless the upload is explicitly aborted.
Committed parts will remain in the OM multi part upload table until an abort or
a complete. If the upload has committed parts but is not completed, that data
will not be deleted until the upload is aborted. If the upload has uncommitted
parts, they would ideally be cleaned out of the open key table periodically,
freeing the space. However, open key cleanup is not fully implemented, so for
now those parts will also remain until the upload is aborted.
