# Superset

Available in VPC

## Connect to external BI - Superset

To connect Data Query from [Superset](https://superset.apache.org/), follow these steps:

1. Sign in to the installed Superset and click **Settings** > **Data - Database Connection** menu at the top right of the screen.
2. Click the **+ Database** button at the top right of the **Databases** menu.
3. Select **trino** from **Supported databases** below.
4. On the **Basic** tab of the **Enter primary credentials** step, enter the display name and the URI below in the **SQLALCHEMY URI** field.
5. After checking the connection status with **Test connection**, click the **Finish** button to complete the creation of the database to connect.
6. Click **SQL** > **SQL Lab** menu at the top of the Superset, and check if the schema and table lists of the created database are viewed normally.

              Note

              

Data Query connection SQLALCHEMY URI

- trino://{SubAccount ACCESS_KEY}:{SubAccount SECRET_KEY}@{Data Query DOMAIN}:443/{User's Data Source name}
  - URI example

```
trino://A6____F8:1B____F3@kr.dataquery.naverncp.com:443/data_catalog
```

              Caution

              

- Depending on how the external BI tool manages the schema, this may result in periodic or frequent query calls.

### Troubleshoot

Depending on the Superset build types(for example, build for production), the trino driver required for Data Query connection may not be included by default. If Database Connection creation fails for this reason, add the driver based on your Superset installation type referring to the following methods:

**1. PyPI installation environment**

- [Superset > Installation (PyPI)](https://superset.apache.org/docs/installation/installation-methods#pypi-python)
- Install `sqlalchemy-trino` package in the environment where Superset is installed.

```
pip install sqlalchemy-trino
```

**2. Docker Compose installation environment**

- [Superset > Installation (Docker Compose)](https://superset.apache.org/docs/installation/docker-compose)
- While deploying Superset in the form of Docker Compose,
- add `sqlalchemy-trino` in requirements-local.txt and run the Docker Compose Up command.

```
echo "sqlalchemy-trino" >> ./docker/requirements-local.txt
```

**3. Kubernetes environment**

- [Superset > Installation (Kubernetes)](https://superset.apache.org/docs/installation/kubernetes#dependencies)
- Add `sqlalchemy-trino` in bootstrapScript in the helm value file.

```
bootstrapScript: |
  #!/bin/bash
  pip install sqlalchemy-trino
```
