> If auto_snapshot is set to true in cassandra.yaml, each time you restart Cassandra, a snapshot is created for system.compactions_in_progress as the table is truncated at cassandra start.
> However as datas in this table are temporary, Cassandra should not create snapshot for this table (or maybe even for system.* tables). This will be coherent with the fact that "nodetool listsnapshots" doesn't even list this table.
> Exemple:
> {code}
> $ nodetool listsnapshots | grep compactions
> $ ls -lh system/compactions_in_progress-55080ab05d9c388690a4acb25fe1f77b/snapshots/
> total 16K
