-----------------------------------
Summary: NodeStore wrapper implementation
Key: OAK-3393
URL: https://issues.apache.org/jira/browse/OAK-3393
Project: Jackrabbit Oak
Issue Type: Improvement
Reporter: Thomas Mueller
I would like to have a node store wrapper implementation. Initial use cases:
* logging (log all NodeStore API calls, possibly with a filter, to be analyzed
later)
* statistics (counting the number of calls, possibly by path)
* profiling (measuring how long calls take)
Later use cases:
* SegmentStore compaction
* on-the-fly migration from one nodestore to another
* maybe: virtual repository (mounting node stores)
I made a first prototype, and found some problems with the NodeStore API and
the way we have used it in Oak. Repository initialization fails with an
IllegalArgumentException if the NodeBuilder does not extend MemoryNodeBuilder.
Also, I have trouble understanding some of the methods (for example rebase,
merge). I think the NodeStore API is much much harder to wrap than (for
example) the DataStore API. I think we should fix that, to make Oak more
modular.
