provides an optimal way to search and retrieve the first non null value ----------------------------------------------------------------------- Key: ISPN-2923 URL: https://issues.jboss.org/browse/ISPN-2923 Project: Infinispan Issue Type: Feature Request Components: Distributed Execution and Map/Reduce Affects Versions: 5.2.5.Final Reporter: Mathieu Lachance Assignee: Vladimir Blagojevic It would be nice if infinispan could provide a way to the common problem of searching and retrieve the first non null value. My attempt was to use the map reduce framework, but it would still scan all the keys and value even if the result as been found. Maybe Infinispan could provide a way to "stop" the map-reduce operation on all nodes when asked, ex, when the first non null value has been found ?
