Connecting Google CloudSQL MySQL

Google CloudSQL MySQL setup requirements

To set up Google CloudSQL MySQL in Stitch, you need:

  • The CREATE USER or INSERT privilege (for the mysql database). The CREATE USER privilege is required to create a database user for Stitch.

  • The GRANT OPTION privilege in Google CloudSQL MySQL. The GRANT OPTION privilege is required to grant the necessary privileges to the Stitch database user.


Step 1: Configure database connection settings

For Stitch to successfully connect with your CloudSQL instance, you’ll need to add our IP addresses to the database’s authorized networks list.

Authorized networks with Stitch IP addresses highlighted in the Google Cloud SQL database connections tab

  1. Sign into your Google Cloud Platform account.
  2. Navigate to the Cloud SQL Instances page.
  3. Click the instance name to open its details page.
  4. Click the Connections tab.
  5. Locate the Public IP section.
  6. For each of the following IP addresses, complete the following:

    1. Click + Add network.
    2. In the Name field, enter a name for the IP address. For example: Stitch 1 for the first IP address, Stitch 2 for the second, and so on.
    3. In the Network field, paste one of the following IP addresses:

      • 52.23.137.21/32

      • 52.204.223.208/32

      • 52.204.228.32/32

      • 52.204.230.227/32

    4. Click Done.
    5. Repeat these steps until all of Stitch’s IP addresses have been added.
  7. When finished, click Save to update the instance.

Step 2: Configure Log-based Incremental Replication

While Log-based Incremental Replication is the most accurate and efficient method of replication, using this replication method may, at times, require manual intervention or impact the source database’s performance. Refer to the Log-based Incremental Replication documentation for more info.

You can also use one of Stitch’s other Replication Methods, which don’t require any database configuration. Replication Methods can be changed at any time.

Step 2.1: Enable automated backups and binary logging

In this step, you’ll enable automated backups and binary logging for the Google CloudSQL MySQL database. This is required to use Log-based Incremental Replication.

  1. On the Instance details page in Google Cloud Platform, click the Edit option at the top of the page.
  2. In the Configuration options section, open Enable auto backups.
  3. If unchecked, check the Automate backups option and select a window for automated backups.

    Note: This is required to use Log-based Incremental Replication.

  4. If unchecked, check the Enable binary logging option.
  5. Click Save.

When binary logging is enabled, Google Cloud SQL will define the required server settings using their pre-defined defaults. Refer to the Server settings list tab for explanations of these parameters and their default values. No other configuration is required on your part.

In the table below are the names, required values, and descriptions of the server settings you must define.

Setting Value Description

Step 2.2: Retrieve server IDs

When Stitch connects to your database and uses Log-based Replication, a unique server ID will be required. This ID ensures that the integration - or integrations, if you’re connecting multiple databases - will not encounter conflicts during the replication process.

To avoid conflicts, you’ll check which server IDs are currently in use and then define a new, unqiue ID in Stitch.

  1. Log into the MySQL server that acts as the replication master.
  2. Run the following statement:

    mysql> SHOW SLAVE HOSTS;
    
  3. The SHOW SLAVE HOSTS statement will return information about servers that are or have been connected as replication slaves:

    +------------+-------------+------+-----------+------------+
    | Server_id  | Host        | Port | Master_id | Slave_UUID |
    +------------+-------------+------+-----------+------------+
    | 192168010  | stitch_prod | 3306 | 192168011 | <UUID>     |
    | 1921680101 | stitch_dev  | 3306 | 192168011 | <UUID>     |
    +------------+-------------+------+-----------+------------+
    

When you complete the setup in Stitch, you’ll define a unique server ID for your Stitch Google CloudSQL MySQL integration to use.

Step 3: Create a Stitch database user

Next, you’ll create a dedicated database user for Stitch. This will ensure Stitch is visible in any logs or audits, and allow you to maintain your privilege hierarchy.

  1. Log into your database as a user with CREATE USER and GRANT OPTION privileges.
  2. Run the following command to create the Stitch database user:

    CREATE USER '<stitch_username>'@'localhost' IDENTIFIED BY '<password>';
    

    Replace [password] with a secure password.

  3. Grant the Stitch user SELECT privileges on the database:

    GRANT SELECT ON *.* TO '<stitch_username>';
    

    To restrict the Stitch user from accessing data in specific objects, you can instead run GRANT commands that only allow access to the data you permit.

    Note: Column-level permissions are not supported for use with Log-based Incremental Replication. Restricting access to columns will cause replication issues.

See the Privileges list tab for an explanation of why these permissions are required by Stitch.

In the table below are the database user privileges Stitch requires to connect to and replicate data from a Google CloudSQL MySQL database.

Privilege name Reason for requirement
SELECT

Required to select rows from tables in a database.

REPLICATION CLIENT

Required for binlog replication. Required to use SHOW BINARY LOGS, which determines that a binary log exists.

REPLICATION SLAVE

Required for binlog replication. Required to use SHOW MASTER STATUS, which fetches the current binlog file and position on the server.

Step 4: Connect Stitch

In this step, you’ll complete the setup by entering the database’s connection details and defining replication settings in Stitch.

Step 4.1: Locate the database connection details in Google

In this step, you’ll locate the Google CloudSQL MySQL database’s IP address in the Google Cloud Platform console. This will be used to complete the setup in Stitch.

Google CloudSQL PostgreSQL Public IP address field

In this step, you’ll locate the Google CloudSQL MySQL database’s public IP address in the Google Cloud Platform console. This will be used to complete the setup in Stitch.

  1. In the CloudSQL Instances page, locate the instance you want to connect to Stitch.
  2. When the instance’s Overview page displays, scroll down to the Connect to this instance section.
  3. Locate the Public IP address field.
  4. Copy and paste the public IP address into a text file or leave this page open and open your Stitch account in another tab.

Step 4.2: Define the database connection details in Stitch

  1. If you aren’t signed into your Stitch account, sign in now.
  2. On the Stitch Dashboard page, click the Add Integration button.

  3. Locate and click the Google CloudSQL MySQL icon.
  4. Fill in the fields as follows:

Step 4.3: Define the Log-based Replication setting

In the Log-based Replication section, you can set this as the integration’s default Replication Method.

When enabled, tables that are set to replicate will use Log-based Incremental Replication by default. If you don’t want a table to use Log-based Incremental Replication, you can change it in the Table Settings page for that table.

If this setting isn’t enabled, you’ll have to select a Replication Method for each table you set to replicate.

Step 4.4: Create a replication schedule

In the Replication Frequency section, you’ll create the integration’s replication schedule. An integration’s replication schedule determines how often Stitch runs a replication job, and the time that job begins.

Google CloudSQL MySQL integrations support the following replication scheduling methods:

To keep your row usage low, consider setting the integration to replicate less frequently. See the Understanding and Reducing Your Row Usage guide for tips on reducing your usage.

Step 5: Select data to replicate

The last step is to select select the tables and columns you want to replicate.

When you track a table, you’ll also need to define its Replication Method and, if using Key-based Incremental Replication, its Replication Key.

You can select tables and columns by:

  1. In the Integration Details page, click the Tables to Replicate tab.
  2. Locate a table you want to replicate.
  3. Click the checkbox next to the object’s name. A green checkmark means the object is set to replicate.
  4. If there are child objects, they’ll automatically display and you’ll be prompted to select some. Note: When you track a table, by default all columns will also be tracked.
  5. After you set a table to replicate, a page with the table’s columns will display. De-select columns if needed.

  6. In the Settings page, define the table’s Replication Method and, if using Key-based Incremental Replication, its Replication Key.

  7. Repeat this process for every table you want to replicate.

  8. Click the Finalize Your Selections button to save your data selections.

Initial and historical replication jobs

After you finish setting up Google CloudSQL MySQL, its Sync Status may show as Pending on either the Stitch Dashboard or in the Integration Details page.

For a new integration, a Pending status indicates that Stitch is in the process of scheduling the initial replication job for the integration. This may take some time to complete.

Free historical data loads

The first seven days of replication, beginning when data is first replicated, are free. Rows replicated from the new integration during this time won’t count towards your quota. Stitch offers this as a way of testing new integrations, measuring usage, and ensuring historical data volumes don’t quickly consume your quota.
