> Issue Type: Improvement
> Components: core, mongomk

>
> There is still a TODO in DocumentNodeStore.readChildren() about memory usage.
> The name offset is already implemented and used when iterating over many
> child nodes. But there are still cases where the readChildren() method itself
> may use too much memory. This happens when there are a lot of documents for
> deleted child nodes. The for loop inside readChildren() will double the
> rawLimit until it is able to fetch the requested nodes and start again with
> an empty list of children. This should be improved to continue after the last
> returned document.
