MySQL

This page describes how to sync data to your MySQL database.

🏃‍♀️ Getting Started

This guide will walk you through connecting to MySQL as a destination.

If you are trying to use MySQL as a data source (to query data from MySQL and sync to elsewhere), that process is documented separately here: MySQL Data Source

1. Visit the Destinations page and click + New Destination.

2. Select MySQL from the menu.

3. Enter the requested database credentials:

Credential	Description
Hostname	Host name or IP address of database
Port	Port of database (3306 by default for MySQL)
Database Name	Name of database within MySQL to connect to
Username	Username Census will use to connect
Password	Password Census will use to connect
Number of Client Connections	Value between 1 and 8 (default is 1). This is the maximum number of concurrent connections Census will use to connect to database. The default should be fine in most cases, but increasing this value can increase throughput on very large syncs.
Use SSH Tunnel	Default: Off - Toggle on to indicate that Census should connect via an SSH Tunnel. For more information, see Network Access Controls
SSH Hostname	Hostname of the Census accessible SSH Tunnel bastion.
SSH Port	Port of SSH Tunnel bastion.
SSH Username	Username Census will use to connect to bastion.

🔑 Permissions

To use MySQL as a destination, Census requires permission to write to the desired destination tables, as well as read metadata about the table and database structures.

-- Note that creating a user may be redundant if you're already configured
-- MySQL as a source.

-- Create census user the ability to sign in with a password
CREATE USER CENSUS IDENTIFIED BY '<strong, unique password>';

-- GRANT access to which ever schemas you'd like to give access to
-- Note: this can also be granted to specific tables as well
GRANT INSERT, UPDATE, SELECT ON <your schema>.* TO CENSUS;
GRANT CREATE TEMPORARY TABLES ON *.* TO CENSUS
