> Seondary NodeStore feature (OAK-4180) currently creates the secondary
> NodeStore upon initialization. This may take long time for existing repo. To
> simplify that we should add support in sidegrade to migrate an existing
> DocumentNodeStore setup to Secondary NodeStore
> This would also allow us to use the sidegraded repository as a clone of
> existing repository with the advantage that it would support incremental
> updates. Currently if a repository is cloned it does not support incremental
> update as NodeState comparison is done based on default implementation
> (actual comparison) as it cannot make use of recordId or revision to optimize
> the diff to determine trees which are not changed between source and target
