 = Configure Cluster Properties
 :description: Learn how to configure cluster properties to enable and manage features.
 
-Redpanda cluster configuration properties are automatically set to the default values and are replicated across all brokers. You can edit certain cluster configuration properties with the Cloud API. For example, you can enable and manage xref:manage:iceberg/about-iceberg-topics.adoc[Iceberg topics], xref:develop:data-transforms/index.adoc[data transforms], and xref:manage:audit-logging.adoc[audit logging]. 
+Cluster configuration properties are set to their default values and automatically replicated across all brokers. You can use cluster properties to enable and manage features such as xref:manage:iceberg/about-iceberg-topics.adoc[Iceberg topics], xref:develop:data-transforms/index.adoc[data transforms], and xref:manage:audit-logging.adoc[audit logging].
+
+For a complete list of the cluster properties you can set in Redpanda Cloud, see xref:reference:properties/cluster-properties.adoc[Cluster Configuration Properties].
 
 == Limitations
 
-Cluster configuration with the Cloud API is supported on BYOC and Dedicated clusters running on AWS and GCP.

-== Set cluster configuration properties
+== Set cluster configuration properties 
+
+You can set cluster configuration properties using the `rpk` command-line tool or the Cloud API.
+
+[tabs]
+======
+`rpk`::
++
+--
+Use `rpk cluster config` to set cluster properties. 
+
+For example, to enable data transforms, set xref:reference:properties/cluster-properties.adoc#data_transforms_enabled[`data_transforms_enabled`] to `true`:
+
+[source,bash]
+----
+rpk cluster config set data_transforms_enabled true
+----
+
+NOTE: Some properties require a rolling restart, and it can take several minutes for the update to complete. The `rpk cluster config set` command returns the operation ID.  
 
-You can set cluster configuration properties when you create a cluster, or you can edit an existing cluster.
+
+--
+Cloud API::
++
+--
+Use the Cloud API to set cluster properties:
 
 * Create a cluster by making a xref:api:ROOT:cloud-controlplane-api.adoc#post-/v1/clusters[`POST /v1/clusters`] request. Edit `cluster_configuration` in the request body with a key-value pair for `custom_properties`.
 
 * Update a cluster by making a xref:api:ROOT:cloud-controlplane-api.adoc#patch-/v1/clusters/-cluster.id-[`PATCH /v1/clusters/{cluster.id}`] request, passing the cluster ID as a parameter. Include the properties to update in the request body.
 
-For a complete list of the cluster configuration properties you can edit in Redpanda Cloud, see xref:reference:properties/cluster-properties.adoc[Cluster Configuration Properties].
+For example, to set xref:reference:properties/cluster-properties.adoc#data_transforms_enabled[`data_transforms_enabled`] to `true`:
+
+[source,bash]
+----
+# Store your cluster ID in a variable.
+export RP_CLUSTER_ID=<cluster-id>
+
+# Retrieve a Redpanda Cloud access token.
+export RP_CLOUD_TOKEN=`curl -X POST "https://auth.prd.cloud.redpanda.com/oauth/token" \
+    -H "content-type: application/x-www-form-urlencoded" \
+    -d "grant_type=client_credentials" \
+    -d "client_id=<client-id>" \
+    -d "client_secret=<client-secret>"`
+
+# Update your cluster configuration to enable data transforms.
+curl -H "Authorization: Bearer ${RP_CLOUD_TOKEN}" -X PATCH \
+  "https://api.cloud.redpanda.com/v1/clusters/${RP_CLUSTER_ID}" \
+ -H 'accept: application/json'\
+ -H 'content-type: application/json' \
+ -d '{"cluster_configuration":{"custom_properties": {"data_transforms_enabled":true}}}'
+----
+
+The xref:api:ROOT:cloud-controlplane-api.adoc#patch-/v1/clusters/-cluster.id-[`PATCH /clusters/{cluster.id}`] request returns the ID of a long-running operation. You can check the status of the operation by polling the xref:api:ROOT:cloud-controlplane-api.adoc#get-/v1/operations/-id-[`GET /operations/\{id}`] endpoint.
+
+NOTE: Some properties require a rolling restart for the update to take effect. This triggers a xref:manage:api/cloud-byoc-controlplane-api.adoc#lro[long-running operation] that can take several minutes to complete.
