Thanks Stephan, I don't want to use POJO classes if I can help it. I want to mimic the following in my configuration file:
CREATE TABLE IF NOT EXISTS Person ( id int, city_id int, name varchar, age int, company varchar, PRIMARY KEY (id, city_id)) WITH "template=partitioned,affinity_key=city_id"; Furthermore, I want to see if it is possible to define affinity over multiple keys, for example, have the above as CREATE TABLE IF NOT EXISTS Person ( id int, city_id int, name varchar, age int, company varchar, PRIMARY KEY (id, city_id)) WITH "template=partitioned,*affinity_key=city_id, country_id"* *;* I have many caches and the relationship between them imply different set of affinity keys. All are defined within the same configuration file.
