Changes to the API for version 7.10edit
Starting in Elasticsearch version 7.10, a new node_roles field has been added to each Elasticsearch element in a deployment plan. The new node_roles field is used in place of the original node_types field when you enable a new feature such as autoscaling, or when you add a new warm and cold data tier.
When you enable one of these new features through the UI, the deployment will automatically update to use the new node_roles field.
If you use the Deployment API to manage your deployment, there are a few important things to note:
-
When migrating from
node_typetonode_roles, it is not possible to go back to usingnode_type. -
The Elasticsearch topology elements must either all use
node_typeor all usenode_roles. -
The
node_rolesfield is supported only on Elasticsearch version 7.10 and above. -
The deployment templates have been updated to also include other elements (for example,
id,node_attributes,topology_element_controller). These elements should also be sent when updating the deployment through the API.
