+= Enable Redpanda SQL on a BYOC cluster
+:description: Enable the Redpanda SQL engine on a BYOC cluster so that users can query streaming data with standard PostgreSQL syntax.
+:page-topic-type: how-to
+
+Enable Redpanda SQL on a BYOC cluster to give your team the ability to query streaming data in Redpanda topics using standard PostgreSQL syntax.
+
+== Prerequisites
+
+To enable Redpanda SQL, you need:
+
+* Admin permissions in your Redpanda Cloud organization.
+* For the Cloud API path, a valid bearer token for the link:/api/doc/cloud-controlplane/topic/topic-cloud-api-overview[Cloud API]. See link:/api/doc/cloud-controlplane/authentication[Authenticate to the API].
+
+== Enable Redpanda SQL
+
+You can enable Redpanda SQL when you create a new BYOC cluster or on an existing cluster.
+
+=== On a new cluster
+
+[tabs]
+=====
+Cloud Console::
++
+--
+. Log in to https://cloud.redpanda.com[Redpanda Cloud^].
+. Start creating a new BYOC cluster on AWS. For details and prerequisites, see xref:get-started:cluster-types/byoc/aws/create-byoc-cluster-aws.adoc[].
+. In the cluster creation form, select the option to enable SQL.
+. Complete the remaining cluster configuration and deploy.
+--
+
+Cloud API::
++
+--
+. Authenticate to the link:/api/doc/cloud-controlplane/topic/topic-cloud-api-overview[Cloud API]. For details, see link:/api/doc/cloud-controlplane/authentication[Authenticate to the API].
+. Make a link:/api/doc/cloud-controlplane/operation/operation-clusterservice_createcluster[`POST /v1/clusters`] request with `oxla.enabled` set to `true` in the cluster spec:
++
+[,bash]
+----
+curl -X POST "https://api.redpanda.com/v1/clusters" \
+  -H "Authorization: Bearer $AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "cluster": {
+      "name": "<cluster-name>",
+      "cloud_provider": "CLOUD_PROVIDER_AWS",
+      "type": "TYPE_BYOC",
+      "region": "<region>",
+      "zones": [ <zones> ],
+      "throughput_tier": "<tier>",
+      "resource_group_id": "<resource-group-id>",
+      "oxla": {
+        "enabled": true
+      }
+    }
+  }'
+----
++
+For the full request body and field reference, see the link:/api/doc/cloud-controlplane/operation/operation-clusterservice_createcluster[Create cluster API].
+. The request returns the ID of a long-running operation. Poll the link:/api/doc/cloud-controlplane/operation/operation-operationservice_getoperation[`GET /v1/operations/{operation.id}`] endpoint until the operation completes.
+--
+=====
+
+=== On an existing cluster
+
+To enable, scale, or disable SQL on an existing cluster, you also need the cluster ID, which you can find in the *Details* section of the cluster overview in the Cloud Console.
+
+. Authenticate to the link:/api/doc/cloud-controlplane/topic/topic-cloud-api-overview[Cloud API]. For details, see link:/api/doc/cloud-controlplane/authentication[Authenticate to the API].
+. Make a link:/api/doc/cloud-controlplane/operation/operation-clusterservice_updatecluster[`PATCH /v1/clusters/{cluster.id}`] request, replacing `{cluster.id}` with your cluster ID:
++
+[,bash]
+----
+curl -X PATCH "https://api.redpanda.com/v1/clusters/{cluster.id}" \
+  -H "Authorization: Bearer $AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"oxla":{"enabled":true}}'
+----
++
+The request returns the ID of a long-running operation. Poll the link:/api/doc/cloud-controlplane/operation/operation-operationservice_getoperation[`GET /v1/operations/{operation.id}`] endpoint until the operation completes:
++
+[,bash]
+----
+curl -X GET "https://api.redpanda.com/v1/operations/{operation.id}" \
+  -H "Authorization: Bearer $AUTH_TOKEN" \
+  -H "Content-Type: application/json"
+----
++
+When the operation is complete, the response shows `"state": "STATE_COMPLETED"`.
+
+== Scale Redpanda SQL
+
+Redpanda SQL supports horizontal scaling from 1 to 12 nodes per cluster. Scaling to 0 is not supported. To remove Redpanda SQL from a cluster, disable the SQL engine instead.
+
+[tabs]
+=====
+Cloud Console::
++
+--
+. Log in to https://cloud.redpanda.com[Redpanda Cloud^].
+. Go to your BYOC cluster and open the *SQL* tab.
+. Set the node count to a value between 1 and 12, then save.
+--
+
+Cloud API::
++
+--
+Make a link:/api/doc/cloud-controlplane/operation/operation-clusterservice_updatecluster[`PATCH /v1/clusters/{cluster.id}`] request with the new replica count. Replace `{cluster.id}` with your cluster ID and `<n>` with a value between 1 and 12:
+
+[,bash]
+----
+curl -X PATCH "https://api.redpanda.com/v1/clusters/{cluster.id}" \
+  -H "Authorization: Bearer $AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"oxla":{"replicas":<n>}}'
+----
+
+The request returns the ID of a long-running operation. Poll link:/api/doc/cloud-controlplane/operation/operation-operationservice_getoperation[`GET /v1/operations/{operation.id}`] until the operation completes.
+--
+=====
+
+== Verify the SQL engine is running
+
+After you enable Redpanda SQL, provisioning may take several minutes. To verify the SQL engine is running:
+
+// TODO: Confirm with engineering if there are any other specific status indicators that users can see in the Console when SQL is running. Is the SQL tab only visible when SQL is enabled?
+
+== Inspect your SQL cluster
+
+Redpanda SQL provides built-in commands to inspect the state of your SQL cluster:
+
+[,sql]
+----
+SHOW NODES;    -- List SQL compute nodes and their status
+SHOW QUERIES;  -- List currently running queries
+----
+
+== Disable Redpanda SQL
+
+[WARNING]
+====
+Disabling Redpanda SQL purges the stored catalog state for the SQL engine and deletes its data from object storage. In-flight queries fail when SQL is disabled. To temporarily stop SQL compute without losing state, <<scale-redpanda-sql,scale the node count down>> instead.
+====
+
+[tabs]
+=====
+Cloud Console::
++
+--
+. Log in to https://cloud.redpanda.com[Redpanda Cloud^].
+. Go to your BYOC cluster and open the *SQL* tab.
+. Click *Remove* and confirm.

+= Redpanda SQL quickstart
+:description: Connect to Redpanda SQL on a BYOC cluster and run your first query on streaming data.
+:page-topic-type: guide
+
+Redpanda SQL is a PostgreSQL-compatible SQL engine built into Redpanda BYOC. It lets you query streaming data in your Redpanda topics with standard SQL, without building ETL pipelines or deploying a separate analytics system. In this quickstart, you connect with `psql` and run your first query against a Redpanda topic.
+
+== Prerequisites
+
+* A Redpanda BYOC cluster on AWS with Redpanda SQL enabled. See xref:sql:get-started/deploy-sql-cluster.adoc[].
+* A Redpanda topic with a schema registered in Schema Registry. If you don't have one, follow the optional <<optional-produce-sample-data,Produce sample data>> section below to create a sample `orders` topic.
+* https://www.postgresql.org/download/[`psql`^] (PostgreSQL client) installed on your local machine.
+
+// TODO: Verify the exact connection string format and where users get credentials.
+// From PRD: SCRAM auth preserved, connection string available in Cloud Console and API response.
+// Confirm with engineering what SCRAM credentials does the user use - superuser auto-created by Control Plane?
+
+[#optional-produce-sample-data]
+== (Optional) Produce sample data
+
+[TIP]
+====
+Skip this section if you already have a Redpanda topic with a schema registered in Schema Registry that you want to query.
+====
+
+If you don't have a schema-registered topic to query yet, follow these steps to create an `orders` topic with a small set of sample records. Redpanda SQL reads the topic's schema from Schema Registry to map fields to SQL columns, so the topic must have a registered schema before you can query it.
+
+This section uses xref:reference:rpk/index.adoc[`rpk`], which you can install by following xref:get-started:rpk-install.adoc[]. You also need a user with permissions to create topics, register schemas, and produce records.
+
+. Create a topic:
++
+[,bash]
+----
+rpk topic create orders
+----
+
+. Save the following Protobuf schema as `order.proto`:
++
+[,proto]
+----
+syntax = "proto3";
+
+message Order {
+  int64 order_id = 1;
+  string customer = 2;
+  string product = 3;
+  int64 amount = 4;       // amount in cents
+  string status = 5;      // "pending", "shipped", "completed"
+}
+----
+
+. Register the schema against the topic's value subject:
++
+[,bash]
+----
+rpk registry schema create orders-value --schema order.proto
+----
+
+. Produce a few sample records. The `--schema-id=topic` flag tells `rpk` to use the topic name strategy to look up the schema you just registered:
++
+[,bash]
+----
+rpk topic produce orders --schema-id=topic <<EOF
+{"order_id": 1, "customer": "alice", "product": "keyboard", "amount": 7500,  "status": "completed"}
+{"order_id": 2, "customer": "bob",   "product": "monitor",  "amount": 32000, "status": "shipped"}
+{"order_id": 3, "customer": "carol", "product": "mouse",    "amount": 4500,  "status": "pending"}
+{"order_id": 4, "customer": "alice", "product": "monitor",  "amount": 32000, "status": "completed"}
+{"order_id": 5, "customer": "dave",  "product": "keyboard", "amount": 7500,  "status": "pending"}
+EOF
+----
+
+When you continue to the next section, use `orders` as the topic name when you define the SQL table.
+
+== Get connection details
+
+After Redpanda SQL is provisioned on your cluster:
+
+. In the Redpanda Cloud Console, go to your cluster and open the *SQL* tab.
+. Copy the connection string.
+
+== Connect to Redpanda SQL
+
+Use `psql` to connect to the SQL engine. Paste the connection string you copied from the Console:
+
+// TODO: Replace with actual connection string format once confirmed with engineering.
+[,bash]
+----
+psql "<connection-string>"
+----
+
+On a successful connection, you should see output similar to:
+
+// TODO: Verify current psql banner text.
+[.no-copy]
+----
+psql (14.x, server 16.0)
+SSL connection (protocol: TLSv1.3)
+Type "help" for help.
+
+=>
+----
+
+== Query a Redpanda topic
+
+When you enable Redpanda SQL, the engine automatically creates a Redpanda catalog named `default_redpanda_connection` that connects to your cluster.
+
+To query a Redpanda topic as a SQL table, define a table against the topic with `CREATE TABLE`. The following example uses the `orders` topic from the previous section. Replace `orders` with the name of your topic, and `orders-value` with the Schema Registry subject that holds the topic's value schema:
+
+[,sql]
+----
+CREATE TABLE default_redpanda_connection=>orders WITH (
+  topic = 'orders',
+  schema_subject = 'orders-value'
+);
+----
+
+Redpanda SQL reads the registered Protobuf schema from Schema Registry and maps each top-level field to a SQL column.
+
+== Run queries
+
+After you create the table, query your topic data with standard SQL. The following examples use the `orders` schema from the optional sample data section. If you're using your own topic, substitute the table name and column names.
+
+View a sample of records:
+
+[,sql]
+----
+SELECT * FROM default_redpanda_connection=>orders LIMIT 10;
+----
+
+Count orders by status:
+
+[,sql]
+----
+SELECT status, COUNT(*) AS total_orders
+FROM default_redpanda_connection=>orders
+GROUP BY status;
+----
+
+Find the largest orders:
+
+[,sql]
+----
+SELECT order_id, customer, product, amount
+FROM default_redpanda_connection=>orders
+WHERE amount > 10000
+ORDER BY amount DESC
+LIMIT 20;
