> URL: https://issues.apache.org/jira/browse/SLING-3380
> Project: Sling
> Issue Type: Improvement
> Components: JCR
> Affects Versions: JCR Resource 2.2.8
> Reporter: Michael Dürig
> Assignee: Carsten Ziegeler
> Fix For: JCR Resource 2.3.2

>
> JcrResourceListener.onEvent(EventIterator) keeps references to all Event instances in the passed iterator. This has turned out as a memory bottleneck e.g. in the scenario where a large sub-tree is copied and NODE_ADDED events for all nodes in that sub-tree are generated.
> Furthermore Oak will be able to handle arbitrarily large transactions (Session.save). In such cases the EventIterator might contains millions of events.
