Thanks for Yingyi's advice. I use the new configuration cc.conf: https://www.dropbox.com/s/xoycm5i0wmr7uet/cc.conf?dl=0 and save about half time for all different scale's multiple joins with different orders on AsterixDB. I update the picture we will use in our VLDB paper https://www.dropbox.com/s/op7x938yxwpwgit/1-10G.eps?dl=0 <https://www.dropbox.com/s/op7x938yxwpwgit/1-10G.eps?dl=0> ( 'W' means wrong order while 'R' means right order. We always put the wrong order join left side to right order join.) You can find AsterixDB is always far more better than other systems. And the plot including 100G is updated here https://www.dropbox.com/s/epbnqvqx5fdgtr4/1-100G.eps?dl=0 (Wrong order also in left)
