Learn how to:

* Create and configure streams for data ingestion
* View and update stream settings
* Delete streams when no longer needed

## Create a stream

Streams are made available to pipelines as SQL tables using the stream name (e.g., `SELECT * FROM my_stream`).

### Dashboard

1. In the Cloudflare dashboard, go to the **Pipelines** page.

   [Go to **Pipelines**](https://dash.cloudflare.com/?to=/:account/pipelines/overview)

2. Select **Create Pipeline** to launch the pipeline creation wizard.

3. Complete the wizard to create your stream along with the associated sink and pipeline.

### Wrangler CLI

To create a stream, run the [`pipelines streams create`](https://developers.cloudflare.com/workers/wrangler/commands/#pipelines-streams-create) command:

```bash
npx wrangler pipelines streams create <STREAM_NAME>
```

Alternatively, to use the interactive setup wizard that helps you configure a stream, sink, and pipeline, run the [`pipelines setup`](https://developers.cloudflare.com/workers/wrangler/commands/#pipelines-setup) command:

```bash
npx wrangler pipelines setup
```

### Schema configuration

Streams support two approaches for handling data:

* **Structured streams**: Define a schema with specific fields and data types. Events are validated against the schema.
* **Unstructured streams**: Accept any valid JSON without validation. These streams have a single `value` column containing the JSON data.

To create a structured stream, provide a schema file:

```bash
npx wrangler pipelines streams create my-stream --schema-file schema.json
```

Example schema file:

```json
{
  "fields": [
    {
      "name": "user_id",
      "type": "string",
      "required": true
    },
    {
      "name": "amount",
      "type": "float64",
      "required": false
    },
    {
      "name": "tags",
      "type": "list",
      "required": false,
      "items": {
        "type": "string"
      }
    },
    {
      "name": "metadata",
      "type": "struct",
      "required": false,
      "fields": [
        {
          "name": "source",
          "type": "string",
          "required": false
        },
        {
          "name": "priority",
          "type": "int32",
          "required": false
        }
      ]
    }
  ]
}
```

**Supported data types:**

* `string` - Text values
* `int32`, `int64` - Integer numbers
* `float32`, `float64` - Floating-point numbers
* `bool` - Boolean true/false
* `timestamp` - RFC 3339 timestamps, or numeric values parsed as Unix seconds, milliseconds, or microseconds (depending on unit)
* `json` - JSON objects
* `binary` - Binary data (base64-encoded)
* `list` - Arrays of values
* `struct` - Nested objects with defined fields

Note

Events that do not match the defined schema are accepted during ingestion but will be dropped during processing. Schema modifications are not supported after stream creation.

## View stream configuration

### Dashboard

1. In the Cloudflare dashboard, go to **Pipelines** > **Streams**.

2. Select a stream to view its associated configuration.

### Wrangler CLI

To view a specific stream, run the [`pipelines streams get`](https://developers.cloudflare.com/workers/wrangler/commands/#pipelines-streams-get) command:

```bash
npx wrangler pipelines streams get <STREAM_ID>
```

To list all streams in your account, run the [`pipelines streams list`](https://developers.cloudflare.com/workers/wrangler/commands/#pipelines-streams-list) command:

```bash
npx wrangler pipelines streams list
```

## Update HTTP ingest settings

You can update certain HTTP ingest settings after stream creation. Schema modifications are not supported once a stream is created.

### Dashboard

1. In the Cloudflare dashboard, go to **Pipelines** > **Streams**.

2. Select the stream you want to update.

3. In the **Settings** tab, navigate to **HTTP Ingest**.

4. To enable or disable HTTP ingestion, select **Enable** or **Disable**.

5. To update authentication and CORS settings, select **Edit** and modify.

6. Save your changes.

Note

For details on configuring authentication tokens and making authenticated requests, see [Writing to streams](https://developers.cloudflare.com/pipelines/streams/writing-to-streams/).

## Delete a stream

### Dashboard

1. In the Cloudflare dashboard, go to **Pipelines** > **Streams**.

2. Select the stream you want to delete.

3. In the **Settings** tab, navigate to **General**, and select **Delete**.

### Wrangler CLI

To delete a stream, run the [`pipelines streams delete`](https://developers.cloudflare.com/workers/wrangler/commands/#pipelines-streams-delete) command:

```bash
npx wrangler pipelines streams delete <STREAM_ID>
```

Warning

Deleting a stream will permanently remove all buffered events that have not been processed and will delete any dependent pipelines. Ensure all data has been delivered to your sink before deletion.
