I love the writeup, having a way to reproduce data if your clusters fail is a definite must with ES.
- notyourwork 10y agoSpot on regarding dedicated masters.
- packetized 10y agoI'd agree with this, but I also had quite a bit of success with using indexer/search nodes as master-eligible, and then basically 'pin' (manually) the master node to one completely dedicated host. That's one complaint about ES, there's no way to set master preference among a set of master-eligible nodes.
- jhgg 10y agoYup. We're thinking about that too. We've been monitoring node performance closely to see when we'll need to shift the topology around a bit. I'd want to keep our clusters small and the topology uniform before I investigate dedicated master nodes though.
- gibrown 10y agoFYI: From my experience (on older ES versions) when you hit problems with it, they will be pretty bad, catastrophic problems. We run dedicated master nodes, but have the master servers running multiple ES instances, so they can serve as masters for multiple clusters.
