public static UntypedResultSet execute(String query, ConsistencyLevel cl,

throws RequestExecutionException
{
return execute(query, cl, internalQueryState(), values);
}

Hi All,
there are two questions CassandraDaemon.

but it not accepted in C * 3.x.anyone know why?
2. I have st

commitlog_segment_size_in_mb is configed in cassandra.yaml.dont think that
it wolud be stored in Cassandra system table.
the following is the introduction of Cassandra System table.

there is a simple config file for testing."cqlstress-example.yaml" under
the tool folder.
you can customize this file to achieve your test
