Well, it can be useful in some scenarios - e.g. temporary tables on nearest or the same node. Best regards, Vladimir Yudovin, Winguzone - Hosted Cloud Cassandra on Azure and SoftLayer. Launch your cluster in minutes. On Sat, 08 Oct 2016 13:44:00 -0400 Jeff Jirsa wrote

I'm sure that's what he meant, I just disagree that it sounds useful -- Jeff Jirsa > On Oct 8, 2016, at 10:33 AM, Vladimir Yudovin wrote: > > As far as I understand Edward meant to have option determinate actual storage > node on client side, by driver, disregarding key hash/tokens mechanism
