How to configure namespace to keep partial data as cache in ram and the remaining in hard disk?

Question

I am trying to write some data to a namespace in Aerospike, but i don't have enough ram for the whole data. How can i configure my Aerospike so that a portion of the data in kept in the ram as cache and remaining is kept in the hard drive? Can I reduce the number of copies of data made in Aerospike kept in ram? It can be done by modifying the contents ofaerospike.conf file but how exactly am i going to achieve it.
