Joerg Hoh commented on OAK-11731:
---------------------------------
[~reschke]from what I understood this mbean, it returns the estimated number of
nodes in the entire subtree below that node, it's not only children.
> expose NodeCounter (getEstimatedChildNodeCounts) in JackrabbitNode

> Key: OAK-11731
> URL: https://issues.apache.org/jira/browse/OAK-11731
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: api, core, jcr
> Reporter: Julian Reschke
> Assignee: Julian Reschke
> Priority: Major
> Fix For: 1.90.0
>
>
> For components attempting to move/copy/delete hierarchies, it would be useful
> for get an estimated child node count either in order to estimate the cost of
> the operation, or by using it to report once the operation is done.
> EDIT: open questions:
> - how useful is that if we only count for one level? A move or delete will
> actually affect the whole tree
> - how do we test on the oak-jcr level? do we need to?
> - for now, there's a new (internal) package export from oak-core. can we do
> better?
