Trello is a project management application based on boards and lists for organizing tasks.

With Erathos, you can integrate Trello data into Clickhouse in just a few minutes. Our platform handles the entire data movement process to your serverless data warehouse, allowing you to blend this data with other sources. This keeps your time focused on what truly drives value — extracting insights and making data-driven decisions.

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

The integration automatically syncs key Trello objects:

- **Projects** — status, assignees, dates, and settings
- **Tasks and subtasks** — priority, status, estimates, and assignees
- **Sprints and cycles** — dates, velocity, and planning data
- **Members** — users, roles, and workload
- **Comments** — history of discussions and decisions
- **Custom fields** — custom properties and tags set up by the team

### Why sync Trello to Clickhouse?

In ClickHouse, you run OLAP queries on your Trello data in milliseconds, which is ideal for high-concurrency dashboards and large-volume time series.

### How it works

Erathos connects to Trello via the official API and syncs your data incrementally — only new or updated records are processed in each run. You choose the sync frequency (from every 5 minutes to daily), the objects to sync, and the destination in Clickhouse. The sync uses incremental replication that processes only new or updated records — keeping 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.
