> 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.
