MySQL is an open source relational database management system (RDBMS) with a client-server model.

Create the Warehouse connection in Hightouch

You'll need to allowlist Hightouch's IP addresses to allow our systems to contact your warehouse. Reference our docs to determine which IPs you need to allowlist.

Any backwards compatible MySQL forks are unofficially supported. An example of this is TiDB by Pingcap.

  1. In Hightouch, go to Sources or click

    Selecting Add Source

  2. Click "Create Source"

    Selecting MySQL Source

  3. Select MySQL

  4. Enter your hostname (IP address or EC2 hostname)

  5. For Port, enter your port. This is 3306 by default

  6. For User, enter your MySQL username

  7. For Password, enter your MySQL password

  8. Click "Test" to test the connection. Hightouch is able to successfully connect, click the "Complete" button at the bottom of the page


If your MySQL cluster is not "publicly accessible", you have two options

  • SSH tunnel: Hightouch will connect to your MySQL cluster via an SSH tunnel established from Hightouch's servers to a bastion server in your VPC.
  • Reverse SSH tunnel: You will establish an SSH connection from a bastion server in your VPC to Hightouch's servers, and Hightouch will reuse that connection to connect to MySQL.

Both of these options are now self-serve and can be referenced here.
