I have tested another case, not sure if this is a bug. I created a few column families on 0.8.0 each has user_name column, in addition, I also enabled secondary index on this column. Then, I upgraded to 0.8.1, when I used cassandra-cli: show keyspaces, I saw index name "user_name_idx" appears for different columns families. It seems the validation rule for index_name on 0.8.1 has been skipped completely.
Is this a bug? or is it intentional? Regards Boris On Sat, Jul 16, 2011 at 10:38 AM, Boris Yen <yulin...@gmail.com> wrote: > Done.
