nodetool cfhistograms

Hello, nodetool cfhistograms ouput shows like below. ks1/cf1 histograms Offset SSTables Write Latency Read Latency Row Size Column Count 1 0 0 0 0 35565129 2 0 0

Can't get performance for scanning the column that is not row key.

Hello, I have cassandra 1.2 and about fifty nodes. I sometime meet requirements for scanning the column that is not row key fast. I know that secondary index doesn't help. someone advised to read sstables directly. is it helpful? I will appreciate for any idea handling this topic. Thanks.
