Subject Re: Indexes and hard disk

As for indexes, cassandra supports columns as indexes (there is a
property called some sort of "type" that can have the value "KEYS".
Start your search in that direction (this is a feature from 0.7)
introduce when you create dinamically columnfamilies and you declare
its columns

On the other hand, if your application will use heavily cassandra i
recommend making a calcularon of the data volumen that will handle and
using a partition that is actually 3 to 5 times bigger. Doing so you
will be able to play around with compactation strategy to avoid
latency when your application is under heavy load.

Hope this information is useful to you
