To assign a node to a data tier, add the respective <<node-roles,node role>> to
the node's `elasticsearch.yml` file. Changing an existing node's roles requires
a <<restart-cluster-rolling,rolling restart>>.

[source,yaml]
----
# Content tier
node.roles: [ data_content ]

# Hot tier
node.roles: [ data_hot ]

# Warm tier
node.roles: [ data_warm ]

# Cold tier
node.roles: [ data_cold ]

# Frozen tier
node.roles: [ data_frozen ]
----

We recommend you use dedicated nodes in the frozen tier. If needed, you can
assign other nodes to more than one tier.

[source,yaml]
----
node.roles: [ data_content, data_hot, data_warm ]

Assign your nodes any other roles needed for your cluster. For example, a small
cluster may have nodes with multiple roles.

[source,yaml]

node.roles: [ master, ingest, ml, data_hot, transform ]
