Removes a leaf node from the cluster without deleting its data.

This command runs the REMOVE LEAF command on the Master Aggregator, which rebalances the leaf node’s partitions into the remaining cluster, and transitions the leaf node to the unknown state.

A leaf node that has been removed can be added back to the cluster, without any loss of data, by using the sdb-admin add-leaf command.

To completely remove a leaf node and its data, refer to the sdb-admin delete-node command.
