I am trying to design a database in which all three of my nodes are primary
and have read/write permission. Moreover, they are consistent with each
other; in other words, all three nodes are in sync and every modification of
data is disseminated amongst all of them. I need the N-to-N setup so that I
can use all three nodes to load balance the write actions.
