This is quorum agreement that a task is done.

Think of providing an interface for a one-shot distributed recursive query. When should the consumer be given "the answer" for some definition thereof?

palvaro commented 13 years ago

don't we already have this module and isn't it called "voting"?

jhellerstein commented 13 years ago

I think it'd use voting and maybe some reliable delivery protocol (perhaps one based on counting). The thing that needs to be voted on is something about acks of dataflow messages.
