Hey friends, new guy here.
I have an ES cluster running on cheap spot instances: 1 master, 5 data nodes, 10 shards, and 1 replica. I have a round robin load balancer in front of my cluster.
During ingest, the load is heavily concentrated on two (small) nodes. I can't figure out why this is the case, as I have shards assigned to every node. Can anyone help me troubleshoot this?
