Subject How to permanently delete one key ?
Date Wed, 28 Apr 2010 02:14:27 GMT
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?

Best Regards

Jeff Zhang
