MariaDB

MariaDB is an open-source relational database compatible with MySQL.

About

MariaDB is a relational database management system derived from MySQL. It implements the MySQL protocol and client libraries and supports modern SQL features with a focus on performance and reliability.

Note: MariaDB is supported using the MySQL source.

Available Tools

mysql-sql Execute pre-defined prepared SQL queries in MariaDB.
mysql-execute-sql Run parameterized SQL queries in MariaDB.
mysql-list-active-queries List active queries in MariaDB.
mysql-list-tables List tables in a MariaDB database.
mysql-list-tables-missing-unique-indexes List tables in a MariaDB database that do not have primary or unique indices.
mysql-list-table-fragmentation List table fragmentation in MariaDB tables.

Requirements

Database User

This source only uses standard authentication. You will need to create a MariaDB user to log in to the database.

Example

sources:
    my_mariadb_db:
        kind: mysql
        host: 127.0.0.1
        port: 3306
        database: my_db
        user: ${MARIADB_USER}
        password: ${MARIADB_PASS}
        # Optional TLS and other driver parameters. For example, enable preferred TLS:
        # queryParams:
        #     tls: preferred
        queryTimeout: 30s # Optional: query timeout duration

Tip

Use environment variables instead of committing credentials to source files.

field	type	required	description
kind	string	true	Must be `mysql`.
host	string	true	IP address to connect to (e.g. “127.0.0.1”).
port	string	true	Port to connect to (e.g. “3307”).
database	string	true	Name of the MariaDB database to connect to (e.g. “my_db”).
user	string	true	Name of the MariaDB user to connect as (e.g. “my-mysql-user”).
password	string	true	Password of the MariaDB user (e.g. “my-password”).
queryTimeout	string	false	Maximum time to wait for query execution (e.g. “30s”, “2m”). By default, no timeout is applied.
