Hi,
I was reminded that there is a Remove API, which can delete the whole rows by specifying the timestamp, key, and column family (in this case, super_column or column are optional). But I found, even I delete all rows for the specified keys with this method, the get_range_slices API will return all the keys with empty column list by specifying the keyRange start and finish with empty. Don't know whether this is expected behavior? Thanks, Regards, Dop
