to do that), i`m using default write_consistency_level, it`s one node cluster(but it happens
also on 2 node cluster), the timestamps for all inserts are returned, no exception in system.log
and output.log in cassandra log directory...
> After that i cannot update these rows(logs from cassandra-cli):
