Hi All,

I am trying to compare Cassandra to another relational database. I am getting 
around 2-3msec response time using Datastax driver, Java 1.7.0_05 64-bit jre 
and the other database is under 500 microseconds for the jdbc SQL 
preparedStatement execute.. One of the major differences is Cassandra uses text 
for the default primary key in the Column family and the SQL table I use int 
which is faster. Can the primary column family key data type be changed to a 
int? I also know Casandra uses varint for IntegerType and not sure that will be 
what I need but I will try it if I can change "key" column to that. If I try 
Int32Type for the primary key I suspect I will need to reload the data after 
that change.

I have looked at the default Java Options in the Cassandra bat file and they 
seem a good starting point but I am just starting to tune now that I can get 
Column Family caching to work.


Regards,
-Tony
