Something like this might work:

Note that only the cells that are needed are pulled into memory: ./bin/nodetool cfstats my_keyspace my_widerow ... Column Family: my_widerow ... Average live cells per slice (last five minutes): 6.0 ... This shows that we are slicing across 6 rows on average for the last couple of select statements. Hope that helps. -- ----------------- Nate McCall Austin, TX @zznate Co-Founder & Sr. Technical Consultant Apache Cassandra Consulting http://www.thelastpickle.com
