I have a Spread cluster comprising 'n' slave nodes and 'N' master nodes. Only one of the master nodes is (can be) the active master at any one time. The other masters are waiting for the master to leave ..... All masters know who is the active master (apart from during a transition). The active master contains significant state information which precludes ad hoc changes of
active master (once a week would be fine ;-) ).
The problem is:
The cluster is required to present a single ip address to the client, this to be used (?) by whichever is the active master.
1) is there any case study telling a best for the above. i have something in mind. but want to know if u ppl can add some meat.
