Data Node Roles

Hello everyone,
We need some hints for a situation.

We have an Elasticsearch cluster with version 7.10 and we configure it for data nodes as follows.

node.master: false true
node.ingest: true

However, when I look at the node details, I see that all other roles are active.

10.x.y.1  16 81 0 0.02 0.01 0.00 cdhilrstw - els-data-1
10.x.y.2  49 80 0 0.00 0.00 0.00 cdhilrstw - els-data-2
10.x.y.3  31 79 0 0.00 0.00 0.00 cdhilrstw - els-data-3
  • Is it a problem if the features I don't use are turned on? For example ml
  • Will this have any performance impact?

Thank you :pray:


Believe the way you are using is deprecated and you should use the node.roles property:

For example:

node.roles: [ data_cold ]

Having all roles will impact your cluster as all nodes will do everything.
