Wide rows does not work well if you start getting past 10,000,000 columns 
though so be very very careful there.  PlayOrm does some wide row indices for 
us and each row length is as large as the number of rows in a partition so 
without playorm you could do partitioning yourself by the way….It's as simple 
as store every row and add to the partitions index.

Subject: Re: Selecting rows efficiently from a Cassandra CF containing time 
series data

 would consider to use wide rows. If you add timestamp to your column name you 
have naturally sorted data. You can easily select any time range without any 
indexes.
