> Priority: Major

> Implement a multi-stage scan for an optimized full diff:
> 1. Full table scan of `toSnapshot.directoryTable`. Use `updateID >
> fromSnapshotDbTxSequenceNumber` filter to build `newList` tracking diff
> candidates. Also populate intermediate column families used for `toSnapshot`
> key's path resolution.
> 2. Full table scan of `fromSnapshot.directoryTable` to build `oldList` for
> diff candidates and intermediate column families used for `fromSnapshot`
> key's path resolution.
> 3. Full table scan of `toSnapshot.keyTable` with `updateID` gating reading
> keys into `newList`.
> 4. Full table scan of `fromSnapshot.keyTable` with reading keys into
> `oldList` for diff candidates.
