[jira] [Created] (HBASE-10288) make mvcc an (optional) part of KV serialization

Sergey Shelukhin created HBASE-10288:
----------------------------------------

             Summary: make mvcc an (optional) part of KV serialization
                 Key: HBASE-10288
                 URL: https://issues.apache.org/jira/browse/HBASE-10288
             Project: HBase
          Issue Type: Improvement
            Reporter: Sergey Shelukhin


This has been suggested in HBASE-10241. Mvcc can currently be serialized in HFile, but the mechanism is... magical. We might want to make it a part of proper serialization of the KV. It can be done using tags, but we may not want the overhead given that it will be in many KVs, so it might require HFileFormat vN+1. Regardless, the external  mechanism would need to be removed while also preserving backward compat.
