How to integrate Metabase with Avro Data

Metabase is an open source data visualization tool that allows users to create interactive dashboards. When paired with CData Connect AI, users can easily create visualizations and dashboards linked to live Avro data. This article describes how to connect to Avro and build a simple visualization using Avro data.

CData Connect provides a pure cloud-to-cloud interface for Avro, allowing you to easily integrate with live Avro data in Metabase — without replicating the data. Connect looks exactly like a SQL Server database to Metabase and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Avro, leveraging server-side processing to quickly return Avro data.

Configure Avro Connectivity for Metabase

Connectivity to Avro from Metabase is made possible through CData Connect AI. To work with Avro data from Metabase, we start by creating and configuring a Avro connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Avro" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Avro. Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Avro Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Avro data from Metabase.

Connect to CData Connect AI from Metabase

After creating the connection in Connect AI, navigate to your Metabase instance. Use the SQL Server interface to connect to Connect AI.

1. Navigate to the administration screen (Settings -> Admin) and click "Add Database" from the "Databases" tab
2. Configure the connection to Connect AI and click "Save"
   • Database type: Select "SQL Server"
   • Name: Name the connection (e.g. "Avro (Connect AI)")
   • Host: tds.cdata.com
   • Port: 14333
   • Database name: The name of the connection you just created (e.g. Avro1)
   • Username: A Connect AI username (e.g. [email protected])
   • Password: The PAT previously created
   • Click to Use a secure connection (SSL)
   

Execute Avro Data with Metabase

Once you configure the connection to Connect AI, you can query Avro and build visualizations.

1. Use the "Write SQL" tool to retrieve the Avro data
2. Write a SQL query based on the Avro connection in CData Connect AI, e.g.
   
   

   SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = 'value_2'

   
3. Navigate to the "Visualization" screen, choose a visualization, and configure the visualization
