MongoDB + ClickHouse
MongoDB is an open-source, document-oriented NoSQL database management system. ClickHouse, on the other hand, is a serverless Big Data solution developed by Google, providing robust storage and data analysis capabilities at scale.
With Erathos, you can integrate data from MongoDB to ClickHouse in just a few minutes. Our platform handles the entire data movement process to your analytical environment, allowing you to blend your data with other sources in your Data Warehouse. This way, your time is focused on what actually drives value — extracting powerful insights and making more data-driven decisions.

What MongoDB data does Erathos sync to ClickHouse?
The integration automatically syncs key MongoDB objects:
- Selected tables — incremental replication of any configured table
- Schema drift — new columns are automatically detected and added to the destination
- Primary keys and timestamps — used for efficient incremental syncs
- Historical data — full initial load followed by incremental updates
Why sync MongoDB to ClickHouse?
In ClickHouse, you can run OLAP queries on MongoDB data in milliseconds, making it ideal for high-concurrency dashboards and high-volume time-series data.
How it works
Erathos connects to MongoDB via the official API and syncs your data incrementally — only new or updated records are processed in each run, keeping pipelines fast and ClickHouse costs predictable. You choose the sync frequency (ranging from 5 minutes to daily), the objects to sync, and the target dataset. Every run is logged with full observability: execution time, rows processed, contextualized errors, and instant alerts via Slack or email if anything goes wrong.
Centralizing MongoDB data into ClickHouse has never been easier
Erathos is a data ingestion platform built for teams that need to replicate operational databases for analytics. With our MongoDB connector, you can incrementally sync transactional tables and records to ClickHouse—complete with schema drift detection and full execution logs.
Data in your data warehouse in minutes
Out-of-the-box MongoDB connector
Replicate MongoDB tables to ClickHouse with incremental synchronization and automatic schema drift detection — without breaking pipelines when the schema changes.
Learn moreFull control over your MongoDB pipelines
Configure frequency and sync mode on a per-table basis. Data lands in ClickHouse optimized for OLAP queries, delivering millisecond-level analytics even across millions of rows.
Learn moreEnd-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.

“Every new source implementation, if I had to do it myself, would take about two or three months. With Erathos, it's done in a few hours. I don't need the skills of a data engineer to generate real value from the company's data.”
“Erathos revolutionized data management at WE. By integrating multiple SaaS tools into a single DW, our technical team now focuses on the core business. We implemented dashboards with insights across every area, enriching our organizational culture and improving our decision-making.”
“We used to have a lot of rework, and now we don't. It's more efficient to work this way. If it's not your core business, hire Erathos. Spend your time modeling your own domain, not someone else's.”
“If I didn't have this infrastructure, I'd need three or four people to do what Erathos does today. I was able to generate real value from my data with a much leaner setup than I thought I'd need. That's the core of building a data-driven culture: the team only uses data when they can trust it.”
“Erathos brought a practical turnaround at CCM. We were able to integrate financial systems, CRM, and processes with BigQuery in just a few clicks, with no technical team required. That gave us a reliable data warehouse that powers automations, dashboards, and even our customer service bots.”
“The robustness and efficiency of Erathos's connectors — whether for Meta, Google, RD Station, or ERPs like Bling and Conta Azul — make the whole process much faster and more reliable. The technical documentation is extremely well put together and intuitive, which makes implementation much easier.”

Frequently Asked Questions
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 complete observability for every run, zero maintenance, and without the opacity of traditional market tools.
Erathos uses incremental replication to sync tables from MongoDB to ClickHouse. Schema drift is automatically detected — if a column is added or modified in MongoDB, the pipeline adapts without manual intervention.
You can configure sync frequencies from every 5 minutes to daily, at the table level. Erathos uses incremental syncs—only new or updated records are processed in each run, keeping your MongoDB pipeline efficient and ClickHouse costs predictable.
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 run is logged with runtime, rows processed, and error context so your team can debug in minutes, not hours.
