Nick Dimiduk updated HBASE-9507:
--------------------------------
Fix Version/s: 0.99.0
> Promote methods of WALActionsListener to WALObserver
> ----------------------------------------------------
>
> Key: HBASE-9507
> URL: https://issues.apache.org/jira/browse/HBASE-9507
> Project: HBase
> Issue Type: Brainstorming
> Components: Coprocessors, wal
> Reporter: Nick Dimiduk
> Priority: Minor
> Fix For: 0.99.0
>
>
> The interface exposed by WALObserver is quite minimal. To implement anything
> of significance based on WAL events, WALActionsListener (at a minimum) is
> required. This is demonstrated by the implementation of the replication
> feature (not currently possible with coprocessors) and the corresponding
> interface exploitation that is the [Side-Effect
> Processor|https://github.com/NGDATA/hbase-indexer/tree/master/hbase-sep].
> Consider promoting the interface of WALActionsListener into WALObserver. This
> goes a long way to being able refactor replication into a coprocessor. This
> also removes the duplicate code path for listeners because they're already
> available via coprocessor hook.
