Jun 18, 2017 · Cluster design is an overlooked part of running Elasticsearch. Offical documentation and blog posts focus on the magic of deploying a cluster in a giffy, while the first problem people face when deploying in production is memory management issues, aka garbage collection madness.
Depending on your needs and budget, an Elasticsearch cluster can consist of a single node, hundreds of nodes, or any number in between. When designing a smaller cluster, you should typically focus on making it resilient to single-node failures. Designers of larger clusters must also consider cases where multiple nodes fail at the same time.
