There are a few ways of doing it. My favorite is to use SelectQuery's with caching enabled, and OSCache as a cache provider:
http://cayenne.apache.org/doc/query-result-caching.html Then you assign each query a cache group String, and configure expiration policies for each cache group. Finally to refresh objects related to the query objects on cache expiration, set desired prefetches for each query. From here - make sure you don't store query results in your code, and access them via a query instead.
