    Oh, you do provide `RootTable.ID` down here. Definitely choose one or the other. The former

> Use case:
> User provisions multiple volumes, some with tmpfs drives, some with SSDs, some with traditional
magnetic spindle hard drives. A volume chooser could use attribute information on tables (ACCUMULO-2841)
to decide which volume to choose when creating new tablets.
