Azure MySQL

Azure MySQL Database is an easy to set up, operate, and scale fully managed database service from Microsoft. It can automate your database management and maintenance, including routine updates, backups and security, enabling you to focusing on working with your data.

You can ingest data from your Azure MySQL database using Hevo Pipelines and replicate it to a Destination of your choice.

Prerequisites

• The Azure MySQL database instance (not the local host) is running. To check this:

  1. Log in to the Microsoft Azure Portal.

  2. In the Overview tab, confirm that the Status field has the value Available.

     

• The MySQL version is 5.7 or higher. You can choose the MySQL version while creating the instance.

• Binary Log (BinLog) replication is enabled, if Pipeline mode is BinLog.

• Hevo’s IP addresses are whitelisted.

• SELECT and REPLICATION privileges are granted to the database user.

• Database hostname and port number of the Source instance are available.

Perform the following steps to configure your Azure MySQL Source:

Create a Read Replica (Optional)

Set up MySQL Binary Logs for Replication

Hevo supports data ingestion from the MySQL database instance via binary logs (BinLog). A binary log is a collection of log files that records information about data modifications and data object modifications made on a MySQL database instance. Typically, binary logs are used for data replication and data recovery.

By default, Row-based BinLog Replication in Azure MySQL. To change this to capture the entire data:

1. Access your Microsoft Azure MySQL instance.

   

2. Under Settings, click Server Parameters.

3. Update the values of the parameters as follows:

   Parameter Name	Value
   binlog_row_image	FULL
   binlog_expire_logs_seconds	A value greater than or equal to 259200 (three days).

   

4. Click Save.

5. Confirm under Notifications that your changes have been applied and the instance has restarted successfully before running the Pipeline, to avoid errors.

   

Whitelist Hevo’s IP Addresses

You need to whitelist the Hevo IP addresses for your region to enable Hevo to connect to your Microsot Azure MySQL database. You can do this by creating firewall rules in your Microsoft Azure database settings as follows:

1. Access your Microsoft Azure MySQL instance.

2. Under Resources, select the database you want to synchronize with Hevo.

   

3. Under Settings, click Connection security.

4. Create a Firewall Rule:

   1. Specify a Firewall Rule Name.

   2. Specify Hevo’s IP addresses in the Start IP and End IP fields as per your region.

      Note: As Hevo has specific IP addresses and not a range, the value in Start IP and End IP fields is the same.

      

   3. Click Save to save the rule.

   4. Repeat this step to add the IP address for each applicable Hevo region.

Create a Database User and Grant Privileges

1. Create a database user (optional)

CREATE USER 'hevo'@'%' IDENTIFIED BY '<password>';

2. Grant privileges to a user

The database user specified in the Hevo Pipeline must have the SELECT and REPLICATION global privileges:

To set these up, open your Azure MySQL database in your SQL client tool like SQL Workbench or the MySQL command line, and then, run the command:

GRANT SELECT, REPLICATION CLIENT, REPLICATION SLAVE ON *.* TO 'username'; # to grant privileges to a user with <username> as username

Note: The REPLICATION SLAVE privilege is required only if you are connecting a read replica. When it is granted to the authenticating user, updates received by a replica server from a source server are logged to the replica’s own binary log.

Retrieve the Hostname and Port Number (Optional)

Specify Azure MySQL Connection Settings

In the Configure your Azure MySQL Source page, specify the following:

• Pipeline Name: A unique name for your Pipeline.

• Database Host: The MySQL host’s IP address or DNS.

  The following table lists a few examples of MySQL hosts:

  Variant	Host
  Amazon RDS MySQL	mysql-rds-1.xxxxx.rds.amazonaws.com
  Azure MySQL	mysql.database.windows.net
  Generic MySQL	10.123.10.001 or mysql-replica.westeros.inc
  Google Cloud MySQL	35.220.150.0

  Note: For URL-based hostnames, exclude the http:// or https:// part. For example, if the hostname URL is http://mysql-replica.westeros.inc, enter mysql-replica.westeros.inc.

• Database Port: The port on which your MySQL server is listening for connections. Default value: 3306.

• Database User: The authenticated user who has the permissions to read tables in your database.

• Database Password: The password for the database user.

• Select an Ingestion Mode: The desired mode by which you want to ingest data from the Source. The available Ingestion Modes are Binlog, Table, and Custom SQL. Read Ingestion Modes.

  For Ingestion mode as Table, read Object Settings for steps to configure the objects to be replicated.

• Database Name: The database you want to load data from if the Pipeline mode is Table or Custom SQL.

• Connection Settings

  • Connect through SSH: Enable this option to connect to Hevo using an SSH tunnel, instead of directly connecting your MySQL database host to Hevo. This provides an additional level of security to your database by not exposing your MySQL setup to the public. Read Connecting Through SSH.

    If this option is disabled, you must whitelist Hevo’s IP addresses. Refer to the content for your MySQL variant for steps to do this.

  • Use SSL: Enable it to use SSL encrypted connection. To enable this, specify the following:

    • CA File: The file containing the SSL server certificate authority (CA).

    • Client Certificate: The client public key certificate file.

    • Client Key: The client private key file.

• Advanced Settings

  • Load All Databases: Applicable for Pipelines with BinLog mode. If this option is enabled, Hevo loads the data from all databases on the selected host. Else, specify a comma-separated list of Database Names you want to load data from.

  • Load Historical Data: Applicable for Pipelines with BinLog mode. If this option is enabled, the entire table data is fetched during the first run of the Pipeline. If disabled, Hevo loads only the data that was written in your database after the time of creation of the Pipeline.

  • Merge Tables: Applicable for Pipelines with BinLog mode. If this option is enabled, Hevo merges tables with the same name from different databases while loading the data to the warehouse. Hevo loads the Database Name field with each record. If disabled, the database name is prefixed to each table name. Read How does the Merge Tables feature work?.

  • Include New Tables in the Pipeline: Applicable for all Ingestion modes except Custom SQL.

    If enabled, Hevo automatically ingests data from tables created in the Source after the Pipeline has been built. These may include completely new tables or previously deleted tables that have been re-created in the Source.

    If disabled, new and re-created tables are not ingested automatically. They are added in SKIPPED state in the objects list, in the Pipeline Overview page. You can update their status to INCLUDED to ingest data.

    You can change this setting later.

Click TEST & CONTINUE to proceed for setting up the Destination.

Limitations

• Logging in using SSL not supported. This setting is enabled by default. You can disable it as follows:

  

  1. Under Settings, click Connection security.

  2. In SSL Settings on the right, set the toggle option for Enforce SSL connection to DISABLED.

  3. Click Save.

• Hevo only fetches tables from the MySQL database. It does not fetch other entities such as functions, stored procedures, views, and triggers.

  To fetch views, you can create individual Pipelines in Custom SQL mode. However, some limitations may arise based on the type of data synchronization, the query mode, or the number of Events. Contact Hevo Support for more details.
