Hi @Kishore Nallan @Fanis Tharropoulos, is there a metrics or a combination of metrics or a field upon which we could determine (or safely infer) that a node is still on the initiating phase of loading the data from the disk to memory?

The /health end point does not return true until data is caught up within the healthy read lag threshold

but, correct me if I wrong, /health could return false in other cases as well or it is there to unambiguously signal that the initiation phase is successfully completed?

It should only return true when node is certainly ready. If it's not, there is a bug. That is the intent of that API.

Thanks a lot!
