Julian Sedding updated OAK-2626:
--------------------------------
Description:
In OAK-2619 I propose to support repeated upgrades into the same NodeStore.
This issue does not optimizate the first run, but any subsequent run benefits
from the proposed changes.
One use-case for this feature is to import all content several days before the
upgrade and then copy only the delta on the day of the upgrade.
Assuming that both the source and target repositories use the same
FileDataStore, binaries could be efficiently compared by their references.
