### 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.
