Hi all, I use the thrift api to remove one key, and then use the get_range_slices to get all the keys and find that the key which I deleted is still there. I refer to the thrift api doc which says get_range_slices will apply to all the keys including the deleted keys. So my question is how can I delete one key permanently, my guess is that cassandra won't delete the key at once just mark the deleted keys. So when will cassandra do the real deletion operation?
