Designing the Perfect Elasticsearch Cluster: the (almost) Definitive Guide
Fred de Villamil 🤔

This is a good overview, but there are a lot of generalizations. I’m currently running a cluster with over 1B documents on only 10 data nodes, and it’s snappy. According to your back-of-napkin calculation, I’d need 200 data nodes.

Also, I tend to use master nodes as request nodes together. Having 3 master nodes that do nothing else but sit around and wait for another master to die seems wasteful, but that depends on your risk tolerance v. cost sensitivity.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
