Beginner question: Do I need an engineer to use Hailuo, or can an ops person handle it?

Great question. As someone who's set up Hailuo for my team (we're a mid-sized e-commerce shop), I can share our experience. The short answer is: **an ops person with the right mindset can definitely handle the core setup, but you'll hit a complexity wall quickly without data engineering principles.**

Here's my breakdown:

**The Ops-Friendly Parts:**
* Initial deployment (Docker/K8s) is well-documented. If you're used to managing containers, it's straightforward.
* Connecting to common data sources (Postgres, MySQL, S3 buckets) is mostly UI-driven. You fill in credentials, test the connection, and you're good.
* Basic dashboard creation is drag-and-drop. An ops person familiar with the business metrics can build useful status boards.

**Where You'll Miss an Engineer:**
* **Data Modeling:** Hailuo gives you raw table access. Without concepts like dimensional modeling, your dashboards become slow and messy. For example, joining 10 tables in a transformation is possible in the UI, but maintaining it is a nightmare.
* **Transformations & Pipelines:** While you can write SQL transforms in Hailuo, managing dependencies and incremental builds gets complex.

```sql
-- Example: A simple incremental model in Hailuo's SQL editor.
-- An ops person can write this, but who ensures it's performant at scale?
{% if is_incremental() %}
SELECT * FROM events
WHERE event_time > (SELECT MAX(event_time) FROM {{ this }})
{% else %}
SELECT * FROM events
{% endif %}
```
* **Performance Tuning:** When dashboard queries slow down, you'll need to understand query plans, indexing, and maybe materialized views.

**My Advice:** An ops person can get it "working" and deliver value for departmental reporting. But if this is becoming a central BI tool, you'll need either:
1. That ops person to actively learn core data engineering (dbt, pipeline design), or
2. Bring in an engineer to set up a robust foundation.

Curious to hear how others have structured this. Did anyone start with ops-only and succeed? What was the breaking point?
