Subject [jira] [Commented] (OAK-1502) Make DataStores available to NodeStores
Date Fri, 14 Mar 2014 14:03:44 GMT

Felix Meschberger commented on OAK-1502:
----------------------------------------

Got it. With a dynamic, optional reference you can implement a bind method which can do the
lazy initialization and termination.

> 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.
