    Description

      To speed up migrations from Jackrabbit 2.x to Oak and to allow multiple Oak repositories to share binaries like what's possible with the Jackrabbit 2.x DataStore mechanism, it would be good if our MKs, most notably MongoMK and SegmentMK, had a way to reference binaries stored in a DataStore instead of in the native blob store of the MK.

      The downside of such setups is of course that it splits up the garbage collection process, but the benefits of a speedier and less expensive migration will likely be worth it at least in some cases with huge amounts (TBs) of existing content.
