From documentation it is not clear whether Ray actors are persistent or not. What is happening when a node that actor runs on crashes?

hi @blublinsky, currently the actor fate shares with the node it runs. That’s said, if a node crashed, all actors hosted by that node are lost.  
Out of curiosity, what’s your usage of ray/ray actors? We have efforts to make ray actor failure tolerant in some specific Ray applications, so would love to hear your use case.
