Connecting MariaDB

MariaDB setup requirements

To set up MariaDB in Stitch, you need:

  • TheCREATE USER orINSERT privilege (for themysql database). TheCREATE USER privilege is required to create a database user for Stitch.

  • TheGRANT OPTION privilege in MariaDB. TheGRANT OPTION privilege is required to grant the necessary privileges to the Stitch database user.

  • TheSUPER privilege in MariaDB. If using binlog replication, theSUPER privilege is required to define the appropriate server settings.

Step 1: Verify your Stitch account's data pipeline region

First, you’ll log into Stitch and verify the data pipeline region your account is using. Later in this guide, you’ll need to grant Stitch access by whitelisting our IP addresses.

The IP addresses you’ll whitelist depend on theData pipeline region your account is in.

  1. Sign into your Stitch account, if you haven’t already.
  2. ClickUser menu (your icon) > Edit User Settings and locate theData pipeline region section to verify your account’s region.

  3. Locate the list of IP addresses for your region:

Keep this list handy - you’ll need it later.

Step 2: Configure database connection settings

In this step, you’ll configure the database server to allow traffic from Stitch to access it. There are two ways to connect your database:

  • A direct connection will work if your database is publicly accessible.
  • An SSH tunnel is required if your database isn’t publicly accessible. This method uses a publicly accessible instance, or an SSH server, to act as an intermediary between Stitch and your database. The SSH server will forward traffic from Stitch through an encrypted tunnel to the private database.

Click the option you’re using below and follow the instructions.

For the connection to be successful, you’ll need to configure your firewall to allow access from our IP addresses.

The IP addresses you’ll whitelist depend on theData pipeline region your account is in.

  1. Sign into your Stitch account, if you haven’t already.
  2. ClickUser menu (your icon) > Edit User Settings and locate theData pipeline region section to verify your account’s region.

  3. Locate the list of IP addresses for your region:

  4. Whitelist the appropriate IP addresses.
  1. Follow the steps in theSetting up an SSH Tunnel for a database connection guide to set up an SSH tunnel for MariaDB.
  2. Complete the steps in this guide after the SSH setup is complete.

Step 3: Configure Log-based Incremental Replication

This step is only required to use logical (Log-based Incremental) replication.

Important:Requirements for configuring binlog replication

To use binlog replication, your MariaDB database must be running MySQL version 5.6.2 or greater.

Additionally, setting up binlog replication requires rebooting your database to ensure parameter changes take effect. To minimize disruptions, we recommend performing the reboot during non-peak usage hours.

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 theLog-based Incremental Replication documentation for more info.

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

Step 3.1: Configure server settings

In this step, you’ll configure your MariaDB server to use Log-based Incremental Replication.

  1. Log into your MariaDB server.

  2. Verify that binlog is enabled by running the following statement. The value returned should be1:

    mysql>select @@log_bin;

    If this statement returns a0, this means that binlog is disabled. You’ll enable it in the next step.

  3. Locate themy.cnf file, usually located at/etc/my.cnf. Verify thatmy.cnf has the following lines in themysqld section:

    [mysqld]binlog_format=ROWbinlog_row_image=FULLexpire_logs_days=7log_bin=mysql-binloglog_slave_updates=1

    A few things to note:

    • log_bin doesn’t have to bemysql-binlog - this value can be anything. Additionally, iflog_bin already has an entry (which you checked in step one), you don’t need to change it.
    • Use eitherexpire_log_days orbinlog_expire_logs_seconds, not both. See theServer settings list tab for more information.
    • Settinglog_slave_updates is only required if you are connecting aread replica. This isn’t required for master instances.
  4. When finished, restart your MariaDB server to ensure the changes take effect.

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

SettingValueDescription
binlog_formatROW

Note: This setting is available on MariaDB databases running version 5.6.2 or greater.

Defines the binary logging format. AROW value enables “event-based” capture, which describes what happens to records in the database.This is necessary to use binlog.

Stitch supports the following event types:

  • INSERT
  • UPDATE
  • DELETE
binlog_row_imageFULL

Note: This setting is available on MariaDB databases running version 5.6.2 or greater.

Defines how row images are written to the binary log. AFULL value ensures that all columns in a row are logged in the before and after images of a change, enabling Stitch to accurately capture all changes made to a record.

expire_logs_days7

Specifies the amount of time, in days, before the automatic removal of binary log files. Stitch recommends a retention period of7 days, but a minimum of3 days will also work.

log_binmysql-binlog

Acts as the “on” switch for binary logging. This is the name of the binary logging file on the database server. For example:mysql-binlog

Note: The name of this file doesn’t have to bemysql-binlog. If your server already specifies alog-bin entry, there’s no need to change it.

log_slave_updates1

Indicates whether updates received by a read replica from a master server should be logged to the replica’s own binary log.

Note: This is applicable when using a read replica.

Step 3.2: Retrieve server IDs

Required for Log-based Replication

This step is required if using Log-based Replication and any of the following are true:

  1. You’re connecting a read replica to Stitch
  2. You’re connecting multiple databases to Stitch, all of which are on the same MariaDB server. These can be read replicas, or databases on the master instance.
  3. You’re adding a new MariaDB Stitch integration, and the database is on the same server as other previously-connected databases.

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>SHOWSLAVEHOSTS;

  3. TheSHOW 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 MariaDB integration to use.

Step 4: Create a Stitch database user

You must have theCREATE USER andGRANT OPTION privileges to complete this step.

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 withCREATE USER andGRANT OPTION privileges.

  2. Run the following command to create the Stitch database user:

    CREATEUSER'<stitch_username>'@'localhost'IDENTIFIEDBY'<password>';

    Replace<password> with a secure password. If using SSH, this can be different than the SSH password.

  3. Grant the Stitch userSELECT privileges by running this command for every table you want to replicate:

    GRANTSELECTON'<database_name>'.'<table_name>'to'<stitch_username>'@'localhost';

    Limiting access to only the tables you want to replicate ensures that the integration can complete discovery (a structure sync) in a timely manner. If you encounter issues in Stitch where tables aren’t displaying, try limiting the Stitch database user’s table access.

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

Important:Using Log-based Incremental Replication

Additionally, if you want to use Log-based Incremental Replication, you’ll also need to grant the Stitch user replication privileges:

GRANTREPLICATIONCLIENT,REPLICATIONSLAVEON*.*TO'<stitch_username>'@'localhost';

See thePrivileges 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 MariaDB database.

Privilege nameReason for requirement
SELECT

Required to select rows from tables in a database.

REPLICATION CLIENT

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

REPLICATION SLAVE

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

Step 5: Connect Stitch

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

Step 5.1: Define the database connection details

  1. If you aren’t signed into your Stitch account,sign in now.

  2. On the Stitch Dashboard page, click theAdd Integration button.

  3. Locate and click theMariaDB icon.

  4. Fill in the fields as follows:

    • Integration Name: Enter a name for the integration. This is the name that will display on the Stitch Dashboard for the integration; it’ll also be used to create the schema in your destination.

      For example, the name “Stitch MariaDB” would create a schema calledstitch_mariadb in the destination.Note: The schema name cannot be changed after the integration is saved.

    • Host (Endpoint): Enter the host address (endpoint) used by the MariaDB instance. For example: This could be a network address such as192.68.0.1, or a server endpoint likedbname.hosting-provider.com.

    • Port: Enter the port used by the MariaDB instance. The default is3306.

    • Username: Enter the Stitch MariaDB database user’s username.

    • Password: Enter the password for the Stitch MariaDB database user.

    • Server ID:Optional: Enter the unique server ID of instance you’re connecting to Stitch.

      This can be any numeric value withinMySQL’s accepted server ID range, as long as it’s unique to the instance. For example: If in theRetrieve Server IDs step there are servers with the IDs192168010 and1921680101, you can enter any other numbers in this field.

Step 5.2: Define the SSH connection details

Note: Skip this step if you’re not using SSH to connect to Stitch.

If you’re using an SSH tunnel to connect your MariaDB database to Stitch, you’ll also need to define the SSH settings. Refer to theSetting up an SSH Tunnel for a database connection guide for assistance with completing these fields.

  1. Click theSSH Tunnel checkbox.

  2. Fill in the fields as follows:

    • SSH Host: Enter the public IP address or hostname of the server Stitch will SSH into.

    • SSH Port: Enter the SSH port on your server. (22 by default)

    • SSH User: Enter the Stitch Linux (SSH) user’s username.

Step 5.3: Define the SSL connection details

Note: Skip this step if you’re not using SSL to connect to Stitch.

Click theConnect using SSL checkbox if you’re using an SSL connection.Note: The database must support and allow SSL connections for this setting to work correctly.

Step 5.4: Define the Log-based Replication setting

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

When enabled, tables that are set to replicate will useLog-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 aReplication Method for each table you set to replicate.

Step 5.5: Create a replication schedule

Replication schedules affect the time Extraction begins, not the time to data loaded. Refer to theReplication Scheduling documentation for more information.

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

MariaDB integrations support the following replication scheduling methods:

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

Step 5.6: Save the integration

When finished, clickCheck and Save.

Stitch will perform a connection test to the MariaDB database; if successful, aSuccess! message will display at the top of the screen.Note: This test may take a few minutes to complete.

Step 6: Select data to replicate

Is an object missing or not replicating? Verify that the object meets the requirements forselection andreplication.

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

Note: If a replication job is currently in progress, new selections won’t be used until the next job starts.

For MariaDB integrations, you can select:

  1. Individual tables and columns

  2. All tables and columns

Click the tabs to view instructions for each selection method.

  1. In the Integration Details page, click theTables to Replicate tab.
  2. Locate a table you want to replicate.

  3. Click thecheckbox next to the table’s name. A blue checkmark means the table is set to replicate.

  4. After you set a table to replicate, a page with the table’s columns will display. De-select columns if needed.

  5. Next, you’ll define the table’s Replication Method. Click theTable Settings button.
  6. In theTable Settings page:

    1. Define the table’sReplication Method, or skip this step if you want to use theintegration’s default method.

    2. If usingKey-based Incremental Replication, select aReplication Key.

    3. When finished, clickUpdate Settings.

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

  8. Click theFinalize Your Selections button at the bottom of the page to save your data selections.

Important: Before using this feature, note that:

  1. Using theSelect All feature will overwrite any previous selections. However, selections aren’t final untilFinalize Your Selections is clicked. ClickingCancel will restore your previous selections.

  2. Log-based Incremental Replication must be enabled and set as the default Replication Method to use the Select All feature.

Refer to theSelect All guide for more info about this feature.

  1. Click into the integration from the Stitch Dashboard page.

  2. Click theTables to Replicate tab.

  3. Navigate to the table level, selecting any databases and/or schemas that contain tables you want to replicate.

  4. In the list of tables, click the box next to theTable Names column.

  5. In the menu that displays, clickTrack AllTables and Fields (Except Views):

    The Track AllTables and Fields (Except Views) menu in the Tables to Replicate tab

  6. Click theFinalize Your Selections button at the bottom of the page to save your data selections.

Initial and historical replication jobs

After you finish setting up MariaDB, itsSync Status may show asPending on either the Stitch Dashboard or in the Integration Details page.

For a new integration, aPending 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 theAnchor 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.

Replication will continue after the seven days are over. If you’re no longer interested in this source, be sure topause ordelete the integration to prevent unwanted usage.
