> The following questions were asked on IRC and I couldn't find a good source of info in
the online book (so I had to answer them, sad I know):
> bq. when a region server goes down, 1) do any queries get affected which are using that
region server, if they do what happens to the transactions 2) how long does it take to switch
over to another region server?
> Brief answers:
> To Q1:
> The queries get retried (I'm not sure if we have a chapter that describes how that works,
might be worth adding however bad it currently is).
> To Q2:
> ZK session timeout + split time + assignment/replay time.
