Why sync eNotas with ClickHouse?
In ClickHouse, you can run OLAP queries on eNotas data in milliseconds, which is ideal for high-concurrency dashboards and high-volume time-series data.
How it works
Erathos connects to eNotas via the official API and syncs your data incrementally — processing only new or updated records on each run. You can choose the sync frequency (ranging from 5 minutes to daily), the objects to sync, and the destination in ClickHouse. The sync leverages incremental synchronization to process only new or updated records — keeping your ClickHouse costs predictable. You choose the sync frequency, the objects to sync, and the destination dataset. Every run is logged with full observability: execution time, rows processed, and alerts via Slack or email.

“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.”
