Important

The SingleStore 9.1 release candidate (RC) gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 9.0 is recommended for production workloads, which can later be upgraded to SingleStore 9.1.

Connect with Superset

On this page

Apache Superset is an open-source business intelligence (BI) and data visualization tool. It enables you to run queries and build interactive dashboards on your SingleStore databases, supporting both SQL-based workflows and visual dataset exploration for the SingleStore database.

To connect with SingleStore, specify the connection URL using the SingleStore SQLAlchemy dialect (singlestoredb://) in the following format:

singlestoredb://<username>:<password>@<hostname>:<port>/<database>

where,

  • hostname: IP address or hostname of the SingleStore cluster.

  • port: Port of the SingleStore cluster. Default is 3306.

  • username: Username of the SingleStore database user with which to connect.

  • password: Password for the SingleStore database user.

Prerequisites

Install the sqlalchemy-singlestoredb package.

Connect Superset to SingleStore

To connect your SingleStore database, configure a database connection in Superset:

  1. Log in to Superset.

  2. From the Settings list, select Database Connections.

  3. On the Databases page, select the + Database button.

  4. On the Connect a database dialog, from the Supported databases list, select SingleStore.

  5. On the Basic tab, enter the following:

    • Display Name: Enter SingleStore.

    • SQLAlchemy URI: Enter the connection URL in the following format:

      singlestoredb://<username>:<password>@<hostname>:<port>/<database>

    • Select Test Connection to verify connectivity to your SingleStore database.

  6. Select Connect.

The SingleStore database is now added as a database connection in Superset. Either create a dataset or query with SQL to explore your SingleStore database. Refer to Superset Documentation for more information.
