Idle node with primary data copy in autoscaler

Ray Core
1

Hello,

A node when idle for default time-out will be removed by the autoscaler. If the data under the idle node is the primary copy, will autoscaler remove such idle nodes?

Thanks

Good question. I think right now, the object store memory resources are automatically updated if there are primary copies on the idle node, so it is not considered as idle (so the answer is no). cc @ericl @Alex

Which part are you specifically talking about?

Hello, If you could help me with code for this part “the object store memory resources are automatically updated if there are primary copies on the idle node” from your reply

The code path is a bit complex. Are you in the Ray public slack channel? I think we can have a call to go through it together.
