MySQL is a popular, open-source relational database (RDMBS). You can connect to any table in any schema in MySQL and create a Gtmhub entity based on it.
How to connect
In Gtmhub, navigate to Setup > Data Sources screen
Click on the Add new Data Source button
From the Choose a Data Source dialog, select MySQL from Databases tab
Enter the necessary information to connect to your MySQL database.
host: host name or IP address of your MySQL instance
schema: the name of the schema to which you want to connect
username: the name of the user with which you wish to connect
password: the password of the user with which you wish to connect
port: the port where MySql is listening. The default is 3306, which is a standard MySQL port
Click on the Connect button.
Choose a table to which you want to connect and click on the Use ... button
Give the name to your data source, something that makes sense to you and select the sync schedule (how often you want this data source to be synced automatically)
Click on the Add my data source button
Note: Contact us for information on Gtmhub's outbound IPs for your account if you need to create a firewall rule to enable external access.
What data from MySQL can I use
You can sync any field from any table in any schema that is accessible to the user with which you connected to MySQL database.
Gtmhub will automatically coerce types for you, so for example date and timestamp can both be mapped to Gtmhub date type.
