Hi Team,

```
"cluster.routing.allocation.enable": "primaries"

In reality does it mean which ever primaries Node is unavailable the cluster will turn its related replica to become primary in that same replica node. There is no over the network data transfer is expected in this situation. Correct me if my understanding is wrong.

TIA
