> There are cases where it is desirable to move partitions between clusters. Having to undo protection and then re-protect tables in order to delete partitions from a source are multi-step and can leave us in a failed open state where partition and table metadata is dirty. By implementing an 'rm -rf'-like functionality, we can perform these operations atomically.
