Hi all,
I’ve always been told that multigets are a Cassandra anti-pattern for
performance reasons. I ran a quick test tonight to prove it to myself, and,
sure enough, slowness ensued. It takes about 150ms to get 100 keys for my use
case. Not terrible, but at least an order of magnitude from wha

After reading through the vnodes and partitioning described in the datastax
documentation, I am still confused about how rows are
partitioned/replicated.
With vnodes, I know that each Node on the ring now supports many token
