Subject cassandra 1.2.5- virtual nodes (num_token) pros/cons?
Date Thu, 25 Jul 2013 21:25:11 GMT
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
