Marcel Reutegger updated OAK-4176:
----------------------------------
Fix Version/s: (was: 1.8)
Unscheduled from 1.8. I don't think there's enough time left and Thomas is
mostly working on index and query topics.
> 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.
