Tomek Rękawek resolved OAK-6636.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.7.7
> Create a path cache for the CompositeNodeState
> ----------------------------------------------
>
> Key: OAK-6636
> URL: https://issues.apache.org/jira/browse/OAK-6636
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: composite
> Reporter: Tomek Rękawek
> Fix For: 1.8, 1.7.7
>
>
> The only non-reference field in the CompositeNodeState is the path. Assuming
> we have many node states in the memory, it may be a bit expensive to store
> their paths in the memory.
> On the other hand, after the recent optimizations (see linked issues), the
> set of the nodes which should be wrapped with the CompositeNodeState is
> limited to:
> * /
> * /oak:index and its direct children
> * /jcr:system
> * /jcr:system/nt:permissionsStore
> That's why it makes sense to use a string cache to store all the paths.
