ONE means write to one replica (in addition to the original).  If you want to 
write to any of them, use ANY.  Is that the right understanding?

I'm super confused by this.. and disturbed that this was my failure scenario :-(

I had one cassandra node for the alpha of my app… and now we're moving into 
beta… which means three replicas.

So I added the second node… but my app immediately broke with:

""Cassandra timeout during write query at consistency ONE (2 replica were 
required but only 1 acknowledged the write)""

… but that makes no sense… if I'm at ONE and I have one acknowledged write, why 
does it matter that the second one hasn't ack'd yet…

?
