MariaDB is is a community-developed, commercially supported fork of the MySQL RDBMS, with the same database structure and indexes as MySQL.
You can ingest data from your MariaDB database using Hevo Pipelines and replicate it to a warehouse of your choice.
The MariaDB server (not localhost) is running. To check this, enter the following command in your MariaDB instance:
sudo systemctl status mariadb
The status must show as
Active: active (running).
The MySQL version is 5.1 or higher. To check this, enter the following command in your MariaDB instance:
mysql -- version
Binary Log (BinLog) replication is enabled, if Pipeline mode is BinLog.
You are assigned the Team Administrator, Team Collaborator, or Pipeline Administrator role in Hevo to create the Pipeline.
Perform the following steps to configure your MariaDB MySQL Source:
Set up MySQL Binary Logs for Replication
A binary log is a collection of log files that records information about data modifications and data object modifications made on a MySQL server instance. Typically binary logs are used for data replication and data recovery.
Hevo supports data ingestion for replication from MySQL servers via binary logs (BinLog). For this, binary logging must be enabled on your MySQL server. You can do this via the MySQL server configuration file or via server startup options to mysqld.
Follow these steps to set up BinLog replication:
1. Check if BinLog replication is already enabled
Open a secure MariaDB shell:
mysql -u username -p
Enter the password for the user:
Enter the command:
If this statement returns a value of 1, BinLog is active. If value returned is 0, this means that BinLog is disabled. To enable it, follow the steps below.
2. Enable BinLog replication
Log in to your MariaDB server.
View your MariaDB server configuration:
sudo nano etc/mysql/mariadb.conf.d/50-server.cnf
(This may be
sudo nano /etc/my.cnfin some cases)
In the configuration file, ensure the following configurations are specified. If not specified, add them now.
[mysqld] binlog_format=ROW binlog_row_image=FULL server-id=1 expire_logs_days=3 log_bin=/var/log/mysql/mysql-bin.log) log_slave_updates=1 max_binlog_size = 100M
log_slave_updatessetting is required only if you are connecting a read replica. When it is set to 1, updates received by a replica server from a source server are logged to the replica’s own binary log.
Restart the MariaDB SQL server instance by entering the following command:
sudo service mysql restart
After restart, log in to the MariaDB server to check BinLog again:
The value returned is now 1, indicating that BinLog is active.
Note: The retention period should ideally be at least 72 hours (3 days). This helps Hevo ensure that no log-file is missed from being read, specially when Historical Data loading is enabled.
Read BinLog to understand how database replication works in MySQL.
The replication reference guide on MySQL’s documentation portal provides a complete reference of the options available for replication and binary logging.
Whitelist Hevo’s IP Addresses
Follow these steps to whitelist the Hevo IP address for your region and enable Hevo to connect to your MariaDB database:
Edit the MariaDB server configuration:
sudo vim etc/mysql/mariadb.conf.d/50-server.cnf
bind-address = 0.0.0.0
bind-address = 10.2.7.152
(Check the Hevo IP address for your region)
Save the file.
Grant Privileges to the User
The database user specified in the Hevo Pipeline must have the following global privileges:
To set up these privileges:
Go to your MariaB MySQL server. For example:
mysql -u root -p
Grant SELECT privileges to the user:
GRANT SELECT ON *.* to jacob@localhost;
(Optional) View the grants for the user:
show grants for jacob@localhost;
Specify MariaDB Connection Settings
In the Configure your MariaDB Source page, specify the following:
Pipeline Name: A unique name for your Pipeline, not exceeding 255 characters.
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 220.127.116.11
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. You can expand this section by clicking SEE MORE to view the list of ingestion modes to choose from. Default value: Bin Log. The available Ingestion Modes are Binlog, Table, and Custom SQL.
For ingestion mode as Table, read Object Settings for steps to configure the objects to be replicated.
Note: For Custom SQL ingestion mode, all Events loaded to the Destination are billable.
Database Name: The database you want to load data from if the Pipeline mode is Table or Custom SQL.
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.
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. If disabled, Hevo fetches the list of all the databases you have access to on the specified database host. From this list, you must select the databases 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 include these objects post-Pipeline creation to ingest data.
You can change this setting later.
Click TEST CONNECTION. This button is enabled once you specify all the mandatory fields. Hevo’s underlying connectivity checker validates the connection settings you provide.
Click TEST & CONTINUE to proceed for setting up the Destination. This button is enabled once you specify all the mandatory fields.
Read the detailed Hevo documentation for the following related topics:
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.
