When data change how ray updates them

How severe does this issue affect your experience of using Ray?

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.

For example, I have an object stored in node 0 and node 1 and it belongs to node 1. A remote task changes the object in node 0. Then another remote task runs in node 1 and use the object, I think the object is changed. I want to know how these objects update.

hi @xyzyx

Ray remote objects are immutable. That means you need to create a new Ray remote object whenever you change it. Objects — Ray 1.13.0 has some details on how to use/update a Ray remote object.
