-------------------------------------

             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.
