Hi Carl,

    With your assistance, I have checked the link to slide and got what I need. As you have
said, it consists of all the key diagrams, and is very helpful for me. 
    Thank you very much!

Best regards!

Hi Jianhua,

I think that all of the wiki attachments were removed in an effort to get rid of spam postings
that had been flooding the wiki. I believe that the diagrams that originally appeared in the
design document are also available in Liyin's Join Optimization presentation, which you can
find on slideshare here:

Hi all,

  Recently I wanted to study the principle of map join optimization, when I found that all
the pictures had disappeared from the webpage --
  Is there somebody knowing what had happened to it? How can I get the correct link to the
page about map join optimization?
