The Problem

MongoDB is great for operational workloads, but running analytical queries directly on your production database is costly and slow. Aggregation pipelines can't match SQL for complex analytics, and connecting BI tools to MongoDB requires additional tooling. Your data team needs the data in BigQuery — but building and maintaining an ETL pipeline takes weeks.

The Solution

NoSQLSync provides a real-time CDC pipeline from MongoDB to BigQuery. Once connected, every insert, update, and delete in MongoDB streams to BigQuery in seconds. Your data team queries fresh operational data in BigQuery using standard SQL, Looker Studio, Tableau, dbt, and the entire Google Cloud analytics ecosystem — without affecting MongoDB performance.

Key Benefits

Real-time dashboards in Looker Studio

Connect Looker Studio directly to BigQuery tables that are updated in real time from MongoDB. No more stale data or overnight batch jobs.

SQL-based analytics for your data team

Your analysts query MongoDB data using standard SQL in BigQuery — JOINs, window functions, CTEs, and all the features they already know and love.

Zero load on your production MongoDB

CDC reads from the oplog, not the collections. Your production MongoDB experiences zero additional query load from analytics.

Combine MongoDB data with other sources

BigQuery excels at joining data from multiple sources. Combine your MongoDB operational data with Google Analytics, CRM data, or log data for holistic analysis.

ML-ready data

BigQuery ML lets you build and run machine learning models directly on your MongoDB data using SQL. No need to export data to a separate ML platform.

Cost-effective at scale

BigQuery's storage is cheap and query pricing is per-query, not per-instance. Keep years of MongoDB data for trend analysis without breaking the bank.

How to set it up

1
Connect MongoDB
Paste your MongoDB Atlas or self-hosted connection string. NoSQLSync auto-detects all collections and their schemas.
2
Connect BigQuery
Provide your GCP service account credentials. NoSQLSync creates the BigQuery dataset and tables using detected schemas.
3
Map your schema
Review how BSON documents map to BigQuery columns. Flatten nested documents, choose ARRAY or JSON for flexible fields, set partitioning and clustering keys.
4
Start real-time sync
Enable CDC. Every MongoDB write appears in BigQuery within seconds. Monitor throughput, latency, and data freshness in the real-time dashboard.

Frequently asked questions

How fresh is the data in BigQuery?

Data reaches BigQuery within seconds of being written to MongoDB. Our CDC pipeline uses BigQuery's Storage Write API for low-latency streaming inserts.

What about nested MongoDB documents?

Nested documents become BigQuery STRUCT columns or JSON columns, depending on your preference. You can also flatten specific nested fields into top-level columns.

Can I use BigQuery's partitioning and clustering?

Yes. During schema mapping, you can designate timestamp columns for partitioning and frequently-filtered columns for clustering — giving you optimal query performance and cost.
