Magento setup requirements
To set up Magento in Stitch, you need:
Permissions in Magento that allow you to create/manage users. This is required to create the Stitch database user.
Step 1: Whitelist Stitch's IP addresses
For the connection to be successful, you’ll need to configure your firewall to allow access from our IP addresses. Whitelist the following IPs before continuing onto the next step:
Step 2: Retrieve your Stitch public key
The Public Key is used to authorize the Stitch Linux user. If the key isn’t properly installed, Stitch will be unable to access your database.
To retrieve the key:
On the Stitch Dashboard page, click the Add Integration button.
Click the MySQL icon.
Click the SSH Tunnel checkbox.
The Public Key will display, along with the other SSH fields.
Leave this page open for now - you’ll need it to wrap things up at the end.
Step 3: Create a Stitch Linux user
Run the following commands as root on your Linux server to create a user named
adduser --disabled-password stitch mkdir /home/stitch/.ssh
Next, import the Public Key into
[PASTE KEY HERE]with the Stitch Public Key:
echo "[PASTE KEY HERE]" >> /home/[stitch_username]/.ssh/authorized_keys
Alter the permissions on the
/home/stitchdirectory to allow access via SSH:
chown -R [stitch_username]:stitch /home/stitch chmod -R 700 /home/stitch/.ssh
Step 4: Create a Stitch database user
- Log into your database as a user with
Run the following command to create the Stitch database user:
CREATE USER '[stitch_username]'@'localhost' IDENTIFIED BY '[password]';
[password]with a secure password. If using SSH, this can be different than the SSH password.
Grant the Stitch user
SELECTprivileges on the database:
GRANT SELECT ON *.* TO '[stitch_username]';
To restrict the Stitch user from accessing data in specific databases, tables, or columns, you can instead run
GRANTcommands that only allow access to the data you permit.
If using Log-based Incremental Replication, you’ll also need to grant the Stitch user replication privileges:
GRANT REPLICATION CLIENT, REPLICATION SLAVE ON *.* TO '[stitch_username]';
Step 5: Connect Stitch
Step 6: 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.
Stitch offers two methods of creating a replication schedule:
- Replication Frequency: This method requires selecting the interval you want replication to run for the integration. Start times of replication jobs are based on the start time and duration of the previous job. Refer to the Replication Frequency documentation for more information and examples.
Anchor scheduling: Based on the Replication Frequency, or interval, you select, this method “anchors” the start times of this integration’s replication jobs to a time you select to create a predictable schedule. Anchor scheduling is a combination of the Anchor Time and Replication Frequency settings, which must both be defined to use this method. Additionally, note that:
- A Replication Frequency of at least one hour is required to use anchor scheduling.
- An initial replication job may not begin immediately after saving the integration, depending on the selected Replication Frequency and Anchor Time. Refer to the Anchor Scheduling documentation for more information.
To help prevent overages, consider setting the integration to replicate less frequently. See the Understanding and Reducing Your Row Usage guide for tips on reducing your usage.
Step 7: Select data to replicate
The last step is to 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.
Replicating MyISAM tables
Because MyISAM tables implement table-level locking when queries are executed, any time Stitch queries a MyISAM table during a replication job, the entire table will be locked.
For this reason, we recommend connecting only read replicas to Stitch to prevent locking tables in your production database. Additionally, consider converting tables to the InnoDB format (which only uses row-level locking) where possible.
You can track tables and columns by:
- In the Integration Details page, click the Tables to Replicate tab.
- Locate a table you want to replicate.
- Click the checkbox next to the object’s name. A green checkmark means the object is set to replicate.
- If there are child objects, they’ll automatically display and you’ll be prompted to select some.
- After you set a table to replicate, the Table Settings page will display. Note: When you track a table, by default all columns will also be tracked.
In the Table Settings page, define the table’s Replication Method and, if using Key-based Incremental Replication, its Replication Key.
Repeat this process for every table you want to replicate.
- Click the Finalize Your Selections button to save your data selections.
Initial and historical replication jobs
After you finish setting up Magento, 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.
Initial replication jobs with Anchor Scheduling
If using Anchor Scheduling, an initial replication job may not kick off immediately. This depends on the selected Replication Frequency and Anchor Time. Refer to the Anchor Scheduling documentation for more information.
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.
Extracting data from Magento
When you connect a database as an input, Stitch only needs read-only access to the databases, tables, and columns you want to replicate. There are two processes Stitch runs during the Extraction phase of the replication process: a structure sync and a data sync.
This is the first part of the Extraction process. During this phase, Stitch will detect any changes to the structure of your database. For example: A new column is added to one of the tables you set to replicate in Stitch. Structure syncs are how Stitch identifies the databases, tables, and columns to display in the Stitch app.
Stitch runs the following queries on Magento databases to perform a structure sync:
SHOW TABLES FROM [database_name]
SHOW KEYS FROM [table_name]
SELECT * FROM INFORMATION_SCHEMA.TABLES
This is the second part of the Extraction process. During this phase, Stitch extracts data from the source and replicates it. The method Stitch uses is the same for all databases, but differs depending on the Replication Method that each table uses.
The tabs below contain info about the queries Stitch runs during the data syncs for each type of Replication Method supported for Magento integrations.
Data syncs for tables using Key-based Incremental
Refer to the Key-based Incremental Replication documentation for more info.
Initial (historical) replication jobs
During the initial replication job for a table using Key-based Incremental Replication, Stitch will replicate the table in full by running a
SELECT query and read out of the resulting cursor in batches:
SELECT column_a, column_b <,...> FROM table_a ORDER BY replication_key_column
Ongoing replication jobs
During subsequent jobs, Stitch will use the last saved maximum value of the Replication Key column to identify new and updated data.
Stitch will run the following query and read out of the associated cursor in batches:
SELECT column_a, column_b <,...> FROM table_a WHERE replication_key_column >= 'last_maximum_replication_key_value' ORDER BY replication_key_column
Data syncs for tables using Full Table
Refer to the Full Table Replication documentation for more info.
For tables using Full Table Replication, Stitch runs a single query and reads out of the resulting cursor in batches:
SELECT column_a, column_b <,...> FROM table_a
This query will be run for each table using Full Table Replication during every replication job, whether it's the initial historical job or a subsequent job.
While we make every effort to ensure the queries that Stitch executes don’t impart significant load on your databases, we still have some recommendations for guaranteeing database performance:
- Use a replica database instead of connecting directly. We recommend using read replicas in lieu of directly connecting production databases with high availability and performance requirements.
- Apply indexes to Replication Key columns. We restrict and order our replication queries by this column, so applying an index to the columns you’re using as Replication Keys can improve performance.
