-------------------------------------
Summary: Refactoring replication WAL reading logic as WAL Iterator
Key: HBASE-13751
URL: https://issues.apache.org/jira/browse/HBASE-13751
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.
