> For pre-filtering for external changes we would need support in ChangeSet for
> # Merging multiple ChangeSet into single - 
> ## This would be used to build up ChangeSet from each commit which would be used in Background Write in DocumentNodeStore
> ## And again while building ChangeSet from multiple JournalEntries while doing Background Read
> ## Care must be taken for overflow handling while merging
> # Serializing and Deserializing ChangeSet as JSON - Care must be taken to distinguish between an empty attribute vs overflown attribute
