Data segmentation with Amoeba MySQL read-write separation

(3) using amoeba to achieve data segmentation, higher level of read and write separation

continue from above the use of amoeba to achieve read and write separation configured for re-configuration:

(client,proxy,two master,two slave Server at least 6 virtual machines)
