Ephemeral nodes and cluster rebalancing — Vertica Forum

Ephemeral nodes and cluster rebalancing

dimitri_pdimitri_p ✭
in General Discussion

In a cluster with k-safety=1, if I change one node to ephemeral, my understanding is that an automatic re-balance will be triggered and data from the ephemeral node will be distributed across the remaining nodes. But I have two questions:

  1. What happens if there are only two remaining nodes and they therefore can not sustain k-safety=1?
  2. Is it possible to prevent the re-balance operation from reading data from the ephemeral node?

Thank you!
