Hi all, I have a question regarding setting the n_val. In the documentation ( http://docs.basho.com/riak/latest/tutorials/fast-track/Tunable-CAP-Controls-in-Riak/) it is stated that:
n_val must be greater than 0 and less than or equal to the number of actual nodes in your cluster to get all the benefits of replication. And, we advise against modifying the n_val of a bucket after its initial creation as this may result in failed reads because the new value may not be replicated to all the appropriate partitions. But this seems contradictory to me. Which value I have to set if I'm setting up one node right now but planning to add second one later? Setting n_val=2 means this value will be greater than actual number of nodes. But setting n_val=1 is also not advisable since I will have to change it later to n_val=2 (I'm planning to have two replicas in the end). I'm also concerned about the performance in case of one node and n_val=2. Will it degrade since both replicas are stored on the same server?
