ScyllaDB have two similar operations, nodetool decommission and nodetool removenode when should each one be used?
Answring myself!
nodetool decommission removes a live node from the cluster, while nodetool removenode removes a dead node.
Both operations are used to remove a node from the cluster; both operations include data streaming. Decommission is preferred since it uses the removed node for streaming; use it when possible.
