- Make sure you are running MySQL 5.7 or higher. Materialize uses [GTID-based binary log (binlog) replication](/sql/create-source/mysql/#change-data-capture), which is not available in older versions of MySQL. - Ensure you have access to your MySQL instance via the [`mysql` client](https://dev.mysql.com/doc/refman/8.0/en/mysql.html), or your preferred SQL client.
