Can we have clustering support for mlb, where there is a cluster leader(who pulls config from marathon) and others update their configs from the master/leader.

My initial thought is that this is more trouble than it's probably worth. Can you describe a use case where this would be a compelling feature? I think it would introduce a lot of complexity, and therefore also introduce a number of new bugs.

The only usecase i could think of, from mlb point of view is

One of the mlb might miss a event/notification (in event mode and in sse mode) and it goes out of sync from the other mlbs.(And it wont get updated untill next event/notification).

But if we think about zdd, the script currently queries all the HAProxy instances to check if the update is propagated, which will have scaling issues once HAProxy instances increase.
