elasticsearchHow do I configure node roles in Elasticsearch?
To configure node roles in Elasticsearch, you can use the node.roles
setting in the elasticsearch.yml
configuration file. This setting is a list of roles that the node should have. The available roles are master
, data
, ingest
and ml
.
For example, to configure a node to be a master and data node, you can add the following to elasticsearch.yml
:
node.roles: [master, data]
This will cause the node to act as both a master and data node.
The following is a list of the available roles and their meanings:
master
: A node with this role will be responsible for managing the cluster, including managing the state of the cluster and assigning shards to nodes.data
: A node with this role will store and index data, and serve search requests.ingest
: A node with this role will process data before it is indexed.ml
: A node with this role will enable machine learning capabilities.
For more information, please refer to the Elasticsearch documentation.
