Subject Re: Read after Write inconsistent at times
Date Fri, 24 Feb 2017 08:07:15 GMT

are your nodes at high load? Are there any dropped messages (nodetool 
tpstats) on any node?

Also have a look at your system clocks. C* needs them in thight sync - 
via ntp for example. Side hint: if you use ntp use the same set of 
upstreams on all of your nodes - ideal your own one. Using 
might lead to minimal dirfts in time across your cluster.

Another thing that could help you out is using client side timestamps: 
(of course only when you are using a single client or all clients are in 
sync via ntp).
