Subject What happens to coordinators and clients when I drain a node?
Date Thu, 23 Nov 2017 06:12:40 GMT
Hi guys,

I have two questions about the drain status.

The doc says when a node is drained it stops accepting new requests and
flush memtable to disk. Does it stops accepting new requests immediately or
wait for the majority of the nodes to gossip about the DRAINED status? If
it stops accepting new requests immediately there could be some noisy
exceptions to the client, right?

After a node is drained, it might take 10 minutes to upgrade and restart
it, during that 10 minutes, what happens to the read and write requests if
the consistency level is ALL?

Thanks & Regards,
Daniel
