By vincent-munier:

When deleting a column, Cassandra leaves the row key behind.
This is expected when using Cassandra and we can't actually delete that row key as well.
Since it deletes by writing tombstones the data is still there until the next compaction. Eventually it will go away completely, but the application code must be aware that an empty row is the same as a deleted row.
