How do I replicate MongoDB data to Databricks?

Sign up for Weld, connect MongoDB as a source and Databricks as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What MongoDB data can I replicate to Databricks?

You can replicate the objects the MongoDB connector exposes. The available objects depend on your MongoDB account permissions and configuration.

How often does Weld replicate data from MongoDB?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.

Can I transform MongoDB data before it lands in Databricks?

Yes. Weld supports SQL-based transformations in the platform and integrates with dbt Cloud. You can clean, join, and model your data before analysis.

Is the MongoDB to Databricks integration secure?

Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.

Use cases

Why replicate MongoDB to Databricks?
Ready for analysis.

Centralizing your MongoDB data in Databricks lets you join it with other data sources for cross-platform analytics and deeper insights.

Build reliable dashboards and reports by querying MongoDB data directly in Databricks using SQL or your preferred BI tool.

Consolidate data from MongoDB alongside other databases and applications in a single cloud data warehouse for a unified analytical layer.

Database replication for analytics
Replicate your MongoDB production data to Databricks without impacting database performance. Query historical data without load on your primary database.
Centralized data warehouse
Bring MongoDB data into Databricks alongside other sources to create a single source of truth for your organization.
Automated reporting
Replace manual exports and spreadsheet-based reporting with automated pipelines from MongoDB to Databricks. Connect BI tools like Looker, Metabase, or Power BI.

Data

What data can you replicate?
From MongoDB to Databricks.

Weld syncs the objects the MongoDB connector exposes into Databricks, and you choose which tables and fields to include. The connector's docs list what is available.

Weld MCP server

Ask your agent.
It queries Databricks for you.

Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It reads the MongoDB context, finds the tables it needs and runs the query in Databricks.

Under the hood

Technical considerations.
What to expect.

Incremental syncing: Weld uses incremental syncing where supported by the MongoDB API, loading only new and updated records to minimize data transfer and warehouse costs.
Change data capture: For MongoDB, Weld can use log-based replication (CDC) to capture inserts, updates, and deletes without querying the entire table on every sync.
Schema handling: Weld automatically manages schema changes. If MongoDB adds new fields, they're detected and added to the corresponding Databricks tables.
Data freshness: Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security: All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
