F, how much data do you store per node and what kind of servers do you use (core count, RAM, disk, ...)?Cheers,TommasoOn Mon, May 29, 2017 at 6:22 PM, Daniel Steuernol <dan...@sendwithus.com> wrote:I am running a 6 node cluster, and I have noticed that the reported load on each node rise
I am running a 6 node cluster, and I have noticed that the reported load on each node rises throughout the week and grows way past the actual disk space used and available on each node. Also eventually latency for operations suffers and the nodes have to be restarted. A couple questions on this,
