[infinispan-issues] [JBoss JIRA] Commented: (ISPN-719) BoundedConcurrentHashMap.EvictionListener should have a bulk entry listener method.

BoundedConcurrentHashMap.EvictionListener should have a bulk entry listener method. ----------------------------------------------------------------------------------- Key: ISPN-719 URL: https://jira.jboss.org/browse/ISPN-719 Project: Infinispan Issue Type: Task Components: Core API Affects Versions: 4.1.0.Final Reporter: Trustin Lee Assignee: Trustin Lee Fix For: 4.2.0.BETA1 BoundedConcurrentHashMap.EvictionListener should have a bulk entry listener so that CacheStores can optimize passivation behavior. Current BoundedConcurrentHashMap notifies EvictionListener for every evicted entry. However, as you see from BoundedConcurrentHashMap.Segment.attemptEviction(..), eviction often happens in bulk. If these evicted entries are supposed to be passivated, it is often beneficial to begin a transaction because it often takes much less time to call commit() less often. If N entries are evicted: without bulk eviction:     store.store(e1); -- each store implied a commit()     store.store(..);     store.store(eN); with bulk eviction:     store.begin(mods(e1, ..., eN), tx, true);
