There was a problem hiding this comment.
I find s.endKey == nil and s.endKey == []byte{} is not distinguished
Should we make it clear? or it's deliberately?
s.endKey == nil -- nobody set it
s.endKey == []byte{} -- it's actually set to a wrong value
There was a problem hiding this comment.
I tries to regards nil and empty the same, so I simply use len to judge whether it's set.
