Introduction This is a quick cheat sheet from Sematext’s Elastic Devops Cheatsheet DevOps cheatsheet Allocation Allocation awareness Avoids putting two copies of the same shard on nodes with the same attribute (e.g. rack, availability zone). For example: node.attr.availability_zone: us-east1 # in elasticsearch.yml Awareness is enabled at the cluster level: curl -XPUT localhost:9200/_cluster/settings?pretty -d '{ "persistent" : { "cluster.routing.allocation.awareness.attributes" : "availability_zone" } }' Allocation filtering Shards of an index can prefer/avoid nodes with certain attributes.
