----------------------------------
Summary: 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
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.
