> The current replication code is all over the place.
> 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 additional wrinkle: The iterator needs to be able to provide the position (file and offset) of the last read edit.
> Once we have this, we use this as a building block to many other changes in the replication code.
