> Before HBASE-2283, each KV had a HLogKey with a replication scope. Now a key
> applies to a list of KVs that spans multiple families so a single scope
> doesn't work anymore. Multiple possible solutions:
> - Each KV have their own scope. We already ruled that out in a previous jira
> since that means the scope would end up in the HFiles.
> - Store pairs of scope/KV in WALEdit instead of straight KVs.
> - Have 2 parallel lists in WALEdit, one for KVs and the other for scopes.
> - Subclass KV and add the scope there, those would be created when inserted
> in the WAL and would contain the KV stored in the HFiles.
> I'm sure there are other solutions, discuss.
