[jira] [Created] (OAK-9745) Efficient operations on child nodes

Angela Schreiber created OAK-9745:
-------------------------------------

             Summary: Efficient operations on child nodes
                 Key: OAK-9745
                 URL: https://issues.apache.org/jira/browse/OAK-9745
             Project: Jackrabbit Oak
          Issue Type: Epic
          Components: core, jcr
            Reporter: Angela Schreiber


as discussed with [~jhoh] in private conversations we should look at more efficient ways to operate on child node collections such as
- determine if the set of child nodes match a given pattern
- determine the number of child nodes
- get an estimate if the number of child nodes exceeds a given max value
- getting an iterator over all child nodes that match a given pattern

one initial idea would be to introduce a new interface representing the child-node collection and adding functionality there instead of creating multiple new methods on {{JackrabbitNode}} or {{JackrabbbitSession}}.

the following improvements requests should be handled as part of this epic:
- OAK-9666
- OAK-9667
