> It would be useful if the WAL protobuf and WALKey class included an optional
> map of extended key/value attributes that downstream coprocessors could use
> to annotate WAL Entries. While standard HBase replication would not use them,
> custom replication endpoints could use the data to make filtering decisions
> or take actions.
> An example use case would be allowing a tool like Phoenix to annotate
> WAL.Entries to indicate that a given Entry is associated with a particular
> Phoenix view rather than the base Phoenix table. (Multiple logical views in
> Phoenix can map to the same physical HBase table.) A custom replication
> endpoint might choose to replicate some views but not others.
