> during removenode and decommission is slow for large vnode cluster with
> NetworkTopologyStrategy. As it needs to build whole replications map for
> every token range.
> In one of our cluster (> 1k nodes), it takes about 20 seconds for each
> NetworkTopologyStrategy keyspace, so the total time to process a removenode
> message takes at least 80 seconds (20 * 4: 3 system keyspaces, 1 user
> keyspace). It blocks the heartbeat propagation and causes false down node.
