This page shows you how to stream data from Azure DB for MySQL to Materialize using the MySQL source.

{{< note >}} GTID-based replication is supported for Azure DB for MySQL flexible server. It is not supported for single server databases. {{</ note >}}
Before creating a source in Materialize, you must configure Azure DB for MySQL for GTID-based binlog replication. Ensure the upstream MySQL database has been configured for GTID-based binlog replication:
{{% mysql-direct/ingesting-data/mysql-configs %}}
For guidance on enabling GTID-based binlog replication in Azure DB, see the Azure documentation.

{{< note >}} If you are prototyping and your Azure DB instance is publicly accessible, you can skip this step. For production scenarios, we recommend configuring one of the network security options below. {{< /note >}}

There are various ways to configure your database's network to allow Materialize to connect:
Allow Materialize IPs: If your database is publicly accessible, you can configure your database's firewall to allow connections from a set of static Materialize IP addresses.
Use an SSH tunnel: If your database is running in a private network, you can use an SSH tunnel to connect Materialize to the database.
Select the option that works best for you.

{{< tab "Allow Materialize IPs">}}
In the SQL Shell, or your preferred SQL client connected to Materialize, find the static egress IP addresses for the Materialize region you are running in:
SELECT * FROM mz_egress_ips;
Update your Azure DB firewall rules to allow traffic from each IP address from the previous step.
{{< /tab >}}
{{< tab "Use an SSH tunnel">}}
To create an SSH tunnel from Materialize to your database, you launch an instance to serve as an SSH bastion host, configure the bastion host to allow traffic only from Materialize, and then configure your database's private network to allow traffic from the bastion host.
Launch an Azure VM with a static public IP address to serve as your SSH bastion host.
Configure the SSH bastion host to allow traffic only from Materialize.

If you are prototyping and already have a cluster to host your MySQL
source (e.g. quickstart), you can skip this step. For production
scenarios, we recommend separating your workloads into multiple clusters for
resource isolation.

Once you have configured your network, create a connection in Materialize per your networking configuration.
