MongoDB + PostgreSQL
MongoDB is an open-source, document-oriented NoSQL database management system. Postgres, in turn, is an open-source relational database management system that is highly robust and scalable. It supports a wide range of data types and advanced features.
With Erathos, you can integrate data from MongoDB into Postgres in just a few minutes. Our platform handles the entire data movement process into your analytics environment and makes it possible to combine that data with other sources in your Data Warehouse. That way, your time goes where it really creates value — uncovering actionable insights and making more data-driven decisions.
Which MongoDB data does Erathos sync with PostgreSQL?
The integration automatically syncs the main MongoDB objects:
Selected tables — incremental replication of any configured table
Schema drift — new columns detected and automatically added to the destination
Primary keys and timestamps — used for efficient incremental sync
Historical data — full initial load followed by incremental updates
Why sync MongoDB with PostgreSQL?
Keeping an analytical copy of MongoDB operational data in PostgreSQL ensures heavy queries don't affect production application performance. With incremental replication and schema drift detection, your data warehouse stays up to date while the transactional database remains stable and responsive.
How it works
Erathos connects to MongoDB through the official API and syncs your data incrementally — only new or updated records are processed in each run, keeping pipelines fast and PostgreSQL costs predictable. You choose the sync frequency (from every 5 minutes to daily), which objects to sync, and the destination dataset. Each run is logged with full observability: execution time, rows processed, errors with context, and instant alerts via Slack or email if anything goes wrong.
No credit card required.
Why do data teams choose Erathos for MongoDB?
MongoDB connector ready to use
Replicate MongoDB tables to PostgreSQL with incremental synchronization and automatic schema drift detection—without breaking pipelines when the structure changes.
Total control over your MongoDB pipelines
Configure sync frequency and type by table. Erathos uses intelligent UPSERT in PostgreSQL—ensuring data consistency even during reprocessing.
End-to-end observability
Stop finding out about MongoDB failures only when the business team complains. Every run is logged with execution time, rows processed, and error context. Get automatic alerts in Slack, Discord, or email the moment anything goes off track — keeping replication up to date without impacting the transactional database.

FAQ
What is Erathos and how can it help my company?
Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect tools like MongoDB to their data warehouse—with full observability into every run, zero maintenance, and none of the opacity of traditional market tools.
How does Erathos synchronize data from MongoDB to PostgreSQL?
Erathos uses incremental replication to sync MongoDB tables to PostgreSQL. Schema drift is automatically detected—if a column is added or modified in MongoDB, the pipeline adapts without manual intervention.
How often does Erathos sync data from MongoDB to PostgreSQL?
You can configure the sync frequency from every 5 minutes up to once per day at the table level. Erathos uses incremental synchronization—only new or updated records are processed in each run, keeping the MongoDB pipeline efficient and PostgreSQL costs predictable.
What happens if a MongoDB synchronization fails?
Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full context—not just "job failed." Smart retries handle transient errors, and every execution is logged with run time, processed rows, and error context so your team can debug in minutes, not hours.
Is there a free trial period for the MongoDB connector?
Yes. Every Erathos connector includes a 14-day free trial. Connect MongoDB to PostgreSQL and start syncing immediately—no credit card required.
