Notion is a tool designed to organize projects, notes, and tasks within a single collaborative and customizable workspace.

With Erathos, you can integrate data from Notion to Clickhouse in just a few minutes. Our platform manages the entire ELT process to your serverless data warehouse, allowing you to easily join this data with other sources. This frees up your time to focus on what actually drives value — extracting insights and making data-driven decisions.

### What Notion data does Erathos sync to Clickhouse?

The integration automatically syncs key Notion objects:

- **Pages and documents** — title, content, and metadata
- **Databases** — records, properties, and views
- **Tasks** — status, assignee, and date
- **Comments** — content, author, and timestamps
- **Users and workspaces** — members, permissions, and activity
- **Blocks and content** — block types and structure

### Why sync Notion to Clickhouse?

In ClickHouse, you can run OLAP queries on your Notion data in milliseconds, making it ideal for high-concurrency dashboards and high-volume time series data.

### How it works

Erathos connects to Notion via its official API and syncs your data incrementally — only new or updated records are processed on each run. You choose the sync frequency (ranging from every 5 minutes to daily), the objects you want to sync, and the destination in Clickhouse. The integration leverages incremental sync to process only new or modified records — keeping Clickhouse costs predictable. You choose the sync frequency, the objects to sync, and the target dataset. Every run is logged with full observability: execution time, rows processed, and alerts via Slack or email.
