MariaDB

Version 23.4.8843

MariaDB

You can use the MariaDB connector from the CData Sync application to capture data from MariaDB and move it to any supported destination. To do so, you need to add the connector, authenticate to the connector, and complete your connection.

Add the MariaDB Connector

To enable Sync to use data from MariaDB, you first must add the connector, as follows:

  1. Open the Connections page of the Sync dashboard.

  2. Click Add Connection to open the Select Connectors page.

  3. Click the Sources tab and locate the MariaDB row.

  4. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the MariaDB connector. For more information about installing new connectors, see Connections.

Authenticate to MariaDB

After you add the connector, you need to set the required properties.

  • Connection Name - Enter a connection name of your choice.

  • Server - Enter the host name or the IP address of your server.

  • Port - Enter the port for the MariaDB database. The default port value is 3306.

CData Sync supports authenticating to MariaDB in several ways. Select your authentication method below to proceed to the relevant section that contains the authentication details.

Password

To connect with your user credentials, set the following properties:

  • Auth Scheme: Select Password.

  • User: Enter the username that you use to authenticate to your MariaDB account.

  • Password: Enter the password that you use to authenticate to your MariaDB account.

Azure Active Directory

To connect with your Azure Active Directory credentials, specify the following properties:

  • Auth Scheme – Select AzureAD.

  • Azure Tenant - Enter the Microsoft Online tenant to which you want to connect. If you do not specify a tenant, CData Sync uses the default tenant.

  • OAuth Client Id - Enter the client Id that you were assigned when you registered your application with an OAuth authorization server.

  • OAuth Client Secret - Enter the client secret that you were assigned when you registered your application with an OAuth authorization server.

Azure Password

To connect with an Azure password, specify these settings:

  • Auth Scheme - Select AzurePassword.

  • Azure Tenant - Enter the identifier (Id) of the Azure Tenant under which your OAuth and client applications were created. This Id is available under Directory (tenant) ID on the Overview page of one of the applications.

Azure Managed Service Identity

To leverage Managed Service Identity (MSI) when CData Sync is running on an Azure virtual machine, select AzureMSI for Auth Scheme. No additional properties are required.

LDAP

To connect with LDAP credentials, specify the following properties:

  • Auth Scheme - Select LDAP.

  • User - Enter the username that you use to authenticate to your MariaDB account.

  • Password - Enter the password that you use to authenticate to your MariaDB account.

Complete Your Connection

To complete your connection:

  1. Specify these properties:

    • Database (optional) - Enter the name of the MariaDB database.

    • Use SSL (optional) - Select whether you want to enable Secure Sockets Layer (SSL). The default value is False.

  2. Define advanced connection settings on the Advanced tab. (In most cases, though, you should not need these settings.)

  3. If you authenticate with AzureAD, click Connect to MariaDB to connect to your MariaDB account.

  4. Click Create & Test to create your connection.

Enable Binary Logging (for Change Data Capture)

Change data capture (CDC) is enabled automatically for the MariaDB database. However, you must enable binary logging for MariaDB replication. Binary logs record transaction updates so replication tools can generate changes. You need the following prerequisites in order to enable binary logging:

  • a MariaDB server

  • the appropriate MariaDB user privileges

Enable Binary Logging

  1. Determine whether binary logging is enabled by submitting the following statement from a MariaDB prompt:

    SHOW VARIABLES LIKE 'log_bin';

    If the option is not enabled (that is, your receive an OFF message), configure the following options in the MariaDB Server configuration file:

    server-id         = 223344
log_bin           = mariadb-bin
binlog_format     = ROW
binlog_row_image  = FULL
expire_logs_days  = 10

    Descriptions of these options are available in MariaDB Binary-Logging Configuration Properties.

  2. Verify that binary logging is enabled by resubmitting this statement:

    SHOW VARIABLES LIKE 'log_bin';

MariaDB Binary-Logging Configuration Properties

This section describes the values for options that are used earlier in step 1:

  • server-id - This value is a unique Id for each server and each replication client in the MariaDB cluster.

  • log_bin - The value for this option is the base name of the sequence of binlog files.

  • binlog_format - The format value for this option is must be set either to ROW or row.

  • binlog_row_image - The value for this option must be set to FULL or full.

  • expire_logs_days - This value is the number of days before the binlog file is removed automatically. The default value is 0, which means that there is no automatic removal. Set the value to match the needs of your environment.
