nodetool cleanup
Immediately cleans up keyspaces and tables that no longer belong to a node.
OpsCenter provides a Cleanup option in the Nodes UI for Running cleanup.
DataStax Enterprise does not automatically remove data from nodes that lose part of their partition range to a newly added node.
After adding a new node, use nodetool cleanup
on the source node and on neighboring nodes that shared the same subrange to prevent the database from including the old data to rebalance the load on that node.
The nodetool cleanup
command temporarily increases the use of disk space proportional to the size of the largest SSTable and may cause an increase in Disk I/O.
