Hi all, More amazing videos coming out of DevNation 2016, this time with the amazing Ray Tsang showing how to auto-scale Infinispan with Kubernetes: http://developers.redhat.com/video/youtube/E4ACZ6_WDyo/ Enjoy! -- Galder Zamarreño Infinispan, Red Hat _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev

Hey Sebastian, Yeah, as Ray rightly says in the video, his approach is based on old Kubernetes versions, and so the current status might be different. What about you write up a blog with a link to the video and you explain the best practices or more recent approaches that we're using these days? A comparison might be handy for our users to better understand the concepts. WDYT?

I've been talking with Andrew about this and he says that settings `-Xms` to some low value and `-Xmx` reasonably high might do the trick. When you add a node to the cluster (assuming only DIST caches) the total amount of used memory in the Pods will (possibly) drop after some time.
