stack commented on HBASE-19494:
-------------------------------
This is follow-on from HBASE-18846.
It is awkward because replicating we operate on WALEntry and WALKey protobufs,
not pojos. I can't pass a filter or CP pb WALEntry or WALKeys. Asking
hbase-indexer crew if I could just pass a few attributes from WALEntry as
params on a simple filter.
> Create simple WALKey filter that can be plugged in on the Replication Sink

> Project: HBase
> Issue Type: Sub-task

>
> hbase-indexer used to look at WALKeys on the sink to see if their time of
> creation was before the time at which the replication stream was enabled.
> In the parent redo, there is no means for doing this anymore (because WALKey
> used to be Private and because to get at the WALKey in the Sink, you had to
> override all of the Replication which meant importing a million Private
> objects...).
> This issue is about adding a simple filter to Replication on the sink-side
> that just takes a WALKey (now InterfaceAudience LimitedPrivate and recently
> made read-only).
> Assigned myself. Need to do this so hbase-indexer can move to hbase2.
