Andrew Purtell commented on HBASE-15995:
----------------------------------------
bq. I also hope to introduce a simplified iterator abstraction on the edit
reading, with an eye towards eventual streaming of edits through a read /
filter / ship pipeline
This is something [~lhofhansl] and I have discussed before. Nice to see someone
picking up the idea.
> Separate replication WAL reading from shipping
> ----------------------------------------------

> Key: HBASE-15995
> URL: https://issues.apache.org/jira/browse/HBASE-15995
> Project: HBase
> Issue Type: Sub-task
> Components: Replication
> Affects Versions: 2.0.0
> Reporter: Vincent Poon
> Fix For: 2.0.0
>
>
> Currently ReplicationSource reads edits from the WAL and ships them in the
> same thread.
> By breaking out the reading from the shipping, we can introduce greater
> parallelism and lay the foundation for further refactoring to a pipelined,
> streaming model.
