Hi, cassandra devs:
I'm learning cassandra and I can understand most of the techniques used.
But I can't understand how cassandra ensures consistency when
adding/removing a node? It seems that when a node joins the dht ring, some
node need to transferring data to the new node using streaming. But the
data may still get updated while transferring, so the new node can never
catch up with it. How cassandra handles this? Will cassandra lose data
during this process?
