Reads during quorum loss

[anupamdialpad]

Hi,

I am wondering what happens in a 7 member cluster if 4 member goes down? and 1 of the 4 member which went down had the leader in it

I know the writes won't work
Will the reads work?

Once a cluster lost the quorum, then it can't serve any write requests and lineariziable read requests. But it can serve serializable read requests, see example below,

$ etcdctl get k1 --consistency="s"
