[infinispan-issues] [JBoss JIRA] (ISPN-8548) Clear post notifications can cause memory issues as it holds all entries locally

Clear post notifications can cause memory issues as it holds all entries locally -------------------------------------------------------------------------------- Key: ISPN-8548 URL: https://issues.jboss.org/browse/ISPN-8548 Project: Infinispan Issue Type: Bug Affects Versions: 9.2.0.Beta1, 9.1.3.Final Reporter: William Burns Assignee: William Burns Fix For: 9.2.0.Beta2, 9.1.4.Final Currently clear iterates over the container and stores all entries before finally invoking clear. This can cause memory issues especially for off heap as we don't want to have all of these entries in the JVM heap at the same time. Something like {code} Iterator<InternalCacheEntry<Object, Object>> iterator = dataContainer.iterator(); while (iterator.hasNext()) { InternalCacheEntry entry = iterator.next(); iterator.remove(); notifier.notifyCacheEntryRemoved(entry.getKey(), entry.getValue(), entry.getMetadata(), false, context, command); } {code}
