Add MySQL Database CDC as source in Real-Time hub (preview)

  • Grein

This article describes how to add MySQL Database Change Data Capture (CDC) as an event source in Fabric Real-Time hub.

The Azure MySQL Database Change Data Capture (CDC) connector allows you to capture a snapshot of the current data in an Azure MySQL database. You specify the tables to be monitored and get alerted when any subsequent row-level changes to the tables. Once the changes are captured in a stream, you can process this CDC data in real-time and send it to different destinations within Fabric for further processing or analysis.

Note

Real-Time hub is currently in preview.

Prerequisites

  • Get access to the Fabric premium workspace with Contributor or above permissions.
  • Created an instance of Azure Database for MySQL – Flexible Server.

Set up MySQL database

The Azure MySQL database connector uses the Debezium MySQL connector to capture changes in your MySQL Database. You must define a MySQL user with permissions on all databases that connector monitors. For step-by-step instructions, see Set up MySQL DB.

Enable the binlog

You must enable binary logging for MySQL replication. The binary logs record transaction updates for replication tools to propagate changes. For example, Azure Database for MySQL.

  1. In the Azure portal, navigate to your Azure MySQL database.

  2. On the left navigation menu, select Server parameters.

  3. Configure your MySQL server with the following properties.

    • binlog_row_image: Set the value to full.
    • binlog_expire_logs_seconds: The number of seconds for automatic binlog file removal. Set the value to match the needs of your environment. For example, 86400.

Use instructions from the Add Azure MySQL Database CDC as a source section.

Microsoft sources page

  1. In Real-Time hub, select Microsoft sources.

  2. In the Source drop-down list, select Azure MySQL DB (CDC).

  3. For Subscription, select an Azure subscription that has the resource group with your Azure MySQL Database account.

  4. For Resource group, select a resource group that has the database.

  5. For Region, select a location where your database is located.

  6. Now, move the mouse over the name of the Azure MySQL DB CDC source that you want to connect to Real-Time hub in the list of databases, and select the Connect button, or select ... (ellipsis), and then select the Connect button.
