Hi,
I have doubt about pglog, the pglog contains (op,object,version) etc. when peering, use pglog to construct missing list,then recover the whole object in missing list even if different data among replicas is less then a whole object data(eg,4MB).
why not add (offset,len) to pglog? If so, the missing list can contain (object, offset, len), then we can reduce recover data.
