-----------------------------------
Summary: Persistent Cache improvements
Key: OAK-4176
URL: https://issues.apache.org/jira/browse/OAK-4176
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core, documentmk
Reporter: Thomas Mueller
Assignee: Thomas Mueller
We want to analyze and improve the persistent cache (specially the node cache):
* Measure how much slower / faster it is compared to the segment store, for
example for traversal of the whole repository.
* Measure the cache miss overhead, and find ways to reduce it.
* Try to improve the data model, specially ordering of the data and granularity.
* Try to reduce usage of 3rd party libraries if it makes sense.
* Hierarchy info is lost in the persistent cache API (currently it's just a
key-value store), so possibly change the API.
