사내 스터디로 ES 책을 보고있는데, 문득 내가 사용하고 있는 ES 들의 role 구성이 궁금했고,
\n생각보다 node 들의 role 이 많아서 정리하려고 한다.

📢 환경

\n\n
\n

✔️ 노드 role 확인

\n

노드 정보 확인 API 를 사용하면 노드의 role 을 확인할 수 있다.

여기서 node.role 필드 값에 대한 정의는 아래와 같다.

✔️ 노드 role 정의

\n

m (master-eligible node)

\n\n
# elasticsearch.yaml\n\nnode.roles: ["master"]
\n

v (voting-only node)

\n\n
# elasticsearch.yaml\nnode.roles: ["master", "voting_only"]
\n

\n \n \n \n \n \n \n \n \n \n

\n

d (data node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data"]
\n

s (data content node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data_content"]
\n

h (data hot node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data_hot"]
\n

w (data warm node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data_warm"]
\n

c (data cold node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data_cold"]
\n

f (data frozen node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "data_frozen"]
\n

i (ingest node)

\n\n
# elasticsearch.yaml\n\nnode.roles: [ "ingest"]
\n

(coordinating node only)

\n\n
# elasticsearch.yaml\n\nnode.roles: []
\n

\n \n \n \n \n \n \n \n \n \n

\n

l (machine learning node)

\n\n
# elasticsearch.yaml\n\nnode.roles: ["ml"]
\n

r (remote cluster client node)

\n\n
# elasticsearch.yaml\n\nnode.roles: ["remote_cluster_client"]
\n

t (transform node)

\n\n
# elasticsearch.yaml\n\nnode.roles: ["transform"]
\n

모든 롤을 가진 node 설정 방법

\n
# elasticsearch.yaml\n\n# 아무런 설정을 하지 않는다. (default)\n# node.roles: []
\n
