MySQL
MySQL is a widely used relational database management system (RDBMS) that is free and open-source, making it ideal for both small and large applications.
Bruin supports MySQL as a source for Ingestr assets, and you can use it to ingest data from MySQL into your data warehouse.
In order to set up MySQL connection, you need to add a configuration item in the .bruin.yml
file and in asset
file.
Follow the steps below to correctly set up MySQL as a data source and run ingestion.
Step 1: Add a connection to .bruin.yml file
To connect to MySQL, you need to add a configuration item to the connections section of the .bruin.yml
file. This configuration must comply with the following schema:
mysql:
- name: "new-mysql"
username: "test_user"
password: "test_password"
host: "localhost"
port: 3306
database: "mysql"
ssl_ca_path: "path/to/ca.pem"
ssl_cert_path: "path/to/cert.pem"
ssl_key_path: "path/to/key.pem"
name
: The name to identify this MySQL connectionusername
: The MySQL username with access to the databasepassword
: The password for the specified usernamehost
: The host address of the MySQL server (e.g., localhost or an IP address)port
: The port number the database server is listening on (default: 3306)database
: The name of the database to connect todriver
: (Optional) The name of the database driver to usessl_ca_path
: (Optional) The path to the CA certificate filessl_cert_path
: (Optional) The path to the client certificate filessl_key_path
: (Optional) The path to the client key file
Step 2: Create an asset file for data ingestion
To ingest data from MySQL, you need to create an asset configuration file. This file defines the data flow from the source to the destination. Create a YAML file (e.g., mysql_ingestion.yml) inside the assets folder and add the following content:
name: public.mysql
type: ingestr
connection: postgres
parameters:
source_connection: new-mysql
source_table: 'mysql.user'
destination: postgres
name
: The name of the asset.type
: Specifies the type of the asset. Set this to ingestr to use the ingestr data pipeline.connection
: This is the destination connection, which defines where the data should be stored. For example:postgres
indicates that the ingested data will be stored in a Postgres database.source_connection
: The name of the MySQL connection defined in .bruin.yml.source_table
: The name of the data table in MySQL that you want to ingest.
Step 3: Run asset to ingest data
bruin run assets/mysql_ingestion.yml
As a result of this command, Bruin will ingest data from the given MySQL table into your Postgres database.
