Federation engine should use a cache with policy defined by connectors/source ----------------------------------------------------------------------------- Key: DNA-38 URL: http://jira.jboss.com/jira/browse/DNA-38 Project: DNA Issue Type: Feature Request Components: Federation Reporter: Randall Hauch Priority: Critical Fix For: 0.2 The federation engine needs to cache the information it obtains from the various connectors, but it should use a caching mechanism that allows the connector to define the caching policy in a flexible way. The DNS system is a great example of how the cached data may contain the caching parameters (TTL, refresh, etc.). The caching mechanism should also support different caching libraries, such as JBoss Cache, Ehcache (http://ehcache.sourceforge.net/), and others.
