Replicate MongoDB Data to Multiple Databases

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live MongoDB data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote MongoDB data from Windows.

Getting Started

---

Configure Replication Destinations

Using CData Sync, you can replicate data from MongoDB to any number of databases, both cloud-based and on-premises. In this example, we use SQLite as the replication destination to demonstrate the process. To add it as a destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select the Destinations tab and locate the SQLite connector.
3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the SQLite connector. For more information about installing new connectors, see Connections in the Help documentation.
4. To connect to SQLite, set the following connection properties:
   • Connection Name: Enter a connection name of your choice.
   • Data Source: Enter the path to the database. You can replicate to an existing database or to a new one. The application must have permission to access the database.

5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to SQLite and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

Configure the MongoDB Connection

You can configure a connection to MongoDB from the Connections tab. To add a connection to your MongoDB account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (MongoDB).
3. Configure the connection properties.
   
   

   Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

   
4. Click Connect to MongoDB to ensure that the connection is configured properly.
5. Click Save & Test to save the changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of MongoDB tables you wish to replicate into SQLite, and click Add Tasks again.

Customize Your Replication

The statement below caches and incrementally updates a table of MongoDB data:

REPLICATE restaurants;

You can specify a file containing the replication queries you want to use to update a particular database. Separate the replication statements with semicolons. The following options are useful when replicating multiple MongoDB accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_restaurants SELECT * FROM restaurants;
  

• Alternatively, use a different schema:

  REPLICATE PROD.restaurants SELECT * FROM restaurants;
  

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your MongoDB data to disparate on-premises, cloud-based, and other databases.

Run the Replication Job

Once all the required configurations are made for the job, select the MongoDB table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.
