> When testing cassandra 4.0 on ccm I noticed that everytime I restart a node,
> truncation snapshots are created for the tables {{system.table_estimates}}
> and {{system.size_estimates}}:
> {noformat}
> $ ccm create -n 1 test -s
> $ ccm node1 stop
> $ ccm node1 start
> $ ccm node1 stop
> $ ccm node1 start
> $ ccm node1 nodetool listsnapshots
> Snapshot Details:
> Snapshot name Keyspace name Column family name True
