Lars Hofhansl commented on HBASE-13751:
---------------------------------------
Thanks [~busbey]. Looks like these are similar, and complimentary. This would
abstract WAL reading into an iterator. And HBASE-12483 would abstract FS use
away from inside the iterator (probably too simplified).
> Refactoring replication WAL reading logic as WAL Iterator

> Project: HBase
> Issue Type: Brainstorming
> Reporter: Lars Hofhansl

> The current replication code is all over.
> A simple refactoring that we could consider is to factor out the part that
> reads from the WALs. Could be a simple iterator interface with one addition
> wrinkle: The iterator needs to be able to provide the position (file and
> offset) if the last read edit.
> Once we have this, we use this as a building block to many other changes in
> the replication code.
