Subject Re: 1000's of column families
Date Thu, 27 Sep 2012 14:01:08 GMT
Out of curiosity, is it really necessary to have that amount of CFs?
I am probably still used to relational databases, where you would use a new
table just in case you need to store different kinds of data. As Cassandra
stores anything in each CF, it might probably make sense to have a lot of
CFs to store your data...
But why wouldn't you use a single CF with partitions in these case?
Wouldn't it be the same thing? I am asking because I might learn a new
modeling technique with the answer.
