Thomas Mueller commented on OAK-1502:
-------------------------------------
> The Whiteboard mechanism maintains a local map
OK, that might work. I thought "dynamic" means calling some (possibly slow)
OSGi method.
> which should be insignificant compared to the cost of loading binaries.
The data store also has a cache, so accessing a binary might also be just a
hash map lookup.
> Make DataStores available to NodeStores

>
> For OAK-805 and related issues we need a mechanism for making Jackrabbit
> DataStores instances available to NodeStore implementations so that they can
> look up references to binaries stored in such datastores.
> In an OSGi environment the best approach is probably to have DataStores as
> OSGi services that the NodeStore can look up dynamically through the
> Whiteboard mechanism. In plain old Java we can just pass a DataStore
> reference to a NodeStore during initialization.
