Re: Using K8s to Manage Cassandra in Production

Hello Hassaan, We use cassandra helm chart[0] for deploying cassandra over kubernetes in production. We have around 200GB cas data. It works really well. You can scale up nodes easily (I haven't tested scaling down). I would say that if you are worried about running cassandra over k8s in producti

Re: Using K8s to Manage Cassandra in Production

Hi, Hassaan! For example we are using C* in k8s in production for our video surveillance system. Moreover, we are using Ceph RBD as our storage for cassandra. Today we have 8 C* nodes each manages 2Tb of data. On Fri, May 18, 2018 at 9:27 AM Hassaan Pasha wrote: > Hi, > > I am trying to craft a
