Disadvantage, hadoop support is based on the token range, so maps may equals numtokens per node * nodes number.

From: rashmi.aros...@gmail.com To: user@cassandra.apache.org Hi,I am upgrading my cassandra cluster from 0.8 to 1.2.5. In cassandra 1.2.5 the 'num_token' attribute confuses me. I understand that it distributes multiple tokens per node but I am not clear how that is helpful for performance or load balancing. Can anyone elaborate? has anyone used this feature and knows its advantages/disadvantages? Thanks, Rashmi
