The values are the same. For each dimension, there is 3 bytes overhead. > 2. what exactly is the difference between the DynamicComposite and Static > Composite ? Static composite type has the types of each dimension specified in the column family definition, so all names within that column family have the same type. Dynamic composite type lets you specify the type for each column, so they can be different. There is extra storage overhead for this and care must be taken to ensure all column names remain comparable. -- Richard Low Acunu | http://www.acunu.com | @acunu
