[jira] [Created] (OAK-5126) Support ChangeSet merging and serialization

Chetan Mehrotra created OAK-5126:
------------------------------------

             Summary: Support ChangeSet merging and serialization 
                 Key: OAK-5126
                 URL: https://issues.apache.org/jira/browse/OAK-5126
             Project: Jackrabbit Oak
          Issue Type: Technical task
          Components: core
            Reporter: Chetan Mehrotra
            Assignee: Stefan Egli
             Fix For: 1.6


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
