Jukka Zitting commented on OAK-1502:
------------------------------------
bq. That's one lookup whenever a binary is needed?
The Whiteboard mechanism maintains a local map of the currently available
services, so the lookup boils down to just a HashMap.get() call, which should
be insignificant compared to the cost of loading binaries.
> Make DataStores available to NodeStores

> Key: OAK-1502
> URL: https://issues.apache.org/jira/browse/OAK-1502
> Project: Jackrabbit Oak
> Issue Type: Sub-task
> Components: core

>
> 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.
