Three Nodes and One Cluster
summary
Live demo of a three-node cluster demo shows Elasticsearch creating an index with three shards, indexing ~100k then 200k documents, and automatically relocating shards when nodes join so CPU and shard counts rebalance across machines. The team runs and demos paramedic and big desk to inspect node metrics, flips replicas to 1 to protect against loss, forces a node shutdown to show green/yellow/red states and a single failed shard in search results, and uses the exclude-allocation API to move shards.
