[erlang-questions] Distributed application and netsplit

This seems like a shame, since distributed application gives you 99% of what you need—it just doesn’t handle recovery from the split brain case in the event of a net split.

It doesn’t seem unreasonable to try to do what you are doing, adding some application-specific logic to determine a winning node, and one or more losing nodes, and to programmatically “reset” the losing nodes such that (1) the application is no longer actively running on them, and (2) failover continues to work going forward.

I can understand if distributed application doesn’t do this out of the box, since this isn’t a one-size-fits-all sort of problem, but surely there is some way to accomplish this without rewriting most of distributed application, no?

By the way, not targeting that question at you Karolis, but rather anyone on the list that may be more familiar with distributed application than we are.
