>                 Key: HBASE-10288
>                 URL: https://issues.apache.org/jira/browse/HBASE-10288
>             Project: HBase
>          Issue Type: Improvement
>          Components: HFile

>            Priority: Minor
> 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.
