About

MySQL is a relational database management system (RDBMS) that stores and manages data. It’s a popular choice for developers because of its reliability, performance, and ease of use.

Available Tools

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

Requirements

Database User

This source only uses standard authentication. You will need to create a MySQL user to login to the database with.

Example

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

Tip

Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file.
