-----------------------------------
Summary: Clear post notifications can cause memory issues as it holds all
entries locally
Key: ISPN-8931
URL: https://issues.jboss.org/browse/ISPN-8931
Project: Infinispan
Issue Type: Bug
Affects Versions: 9.1.3.Final, 9.2.0.Beta1
Reporter: William Burns
Assignee: William Burns
Fix For: 9.1.4.Final, 9.2.0.Beta2
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}
