---------------------------------------
Summary: WALKey Extended Attributes
Key: HBASE-22622
URL: https://issues.apache.org/jira/browse/HBASE-22622
Project: HBase
Issue Type: New Feature
Components: wal
Reporter: Geoffrey Jacoby
Assignee: Geoffrey Jacoby
It would be useful if the WAL protobuf and WALKey class included an optional
map of extended key/value attributes. 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 table. A custom replication endpoint might
choose to replicate some views but not others.
