Description

The current implementation of MongoNodeState.getChildNodeEntries() gets all the child nodes at once and does not work well when there are many child nodes. Where 'many' is e.g. one million or more.

Direct lookup of a child node with many siblings already works fine. This issue is only about enumerating potentially all child nodes.
