You can certainly serve more reads with a 4th node, but I'm not sure
what you mean by "it won't have a voting role". It still participates
in voting for leaders as do all non-observers regardless of whether it
is an even or odd number. With zookeeper there is no voting on each
transaction, only leader changes.
