Use CData Sync for automated, continuous, customizable MongoDB replication to delimited files (CSV/TSV).

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live MongoDB data into local delimited files (CSV/TSV), allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

About MongoDB Data Integration

Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:

MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

Getting Started


Configure CSV/TSV as a Replication Destination

Using CData Sync, you can replicate MongoDB data to delimited files, like CSV or TSV. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select CSV as a destination. 👁 Configure a Destination connection to CSV.
  3. Enter the necessary connection properties. To connect to a directory for storing delimited files, set the following:
    • Destination Folder: Set this location on the disk for the delimited files.
    • Include Column Headers: Set this to True for the first row in each file to represent the column names.
  4. Click Test Connection to ensure that the connection is configured properly. 👁 Configure a Destination connection.
  5. Click Save Changes.

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 ensure that the connection is configured properly.
  5. Click Save 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.

👁 Select Source and Destination connections for the replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

👁 Choose entire tables to replicate (Salesforce is shown).

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication. 👁 Configure a replication Transform.

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

👁 Schedule your job to run automatically.

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 delimited files.
