Stefan Guggisberg commented on OAK-167:
---------------------------------------
IMO we have no choice but buffer transient changes (-> 'transient space') in
oak-jcr. otherwise i don't see how we could efficiently remote the JCR api.
buffering the transient changes in oak-core would mean that every Node.addNode
and Node.setProperty would trigger a server round-trip. that's not an option.
see also OAK-162.
> Caching NodeStore implementation

> For remote MicroKernel implementations and other cases where local caching of
> content is needed it would be useful to have a NodeStore implementation that
> maintains a simple in-memory or on-disk cache of frequently accessed content.
> Such a NodeStore implementation could also be used to better isolate the
> current caching logic behind uncommitted changes.
