How It Works

"In data engineering, the difference between a good deployment and a disaster often comes down to one thing: visibility. That's where Recce changes the game."
🚀 The PR Review Bottleneck Nobody Talks About
Let me paint you a familiar picture: It's 4:30 PM on Friday. Your team just submitted a dbt PR that touches 15 models. The CI tests pass, but your gut says there's more to check. Do you:
- Manually compare production vs development datasets?
- Try to mentally map downstream impacts?
- Cross your fingers and merge?
We've all been there. Traditional dbt PR reviews are like flying blind - you see the code changes but lack contextual awareness of their data impact. This is the exact pain point Recce was born to solve.
🔍 Recce Explained: Your Data Change Microscope
Recce isn't just another validation tool - it's a context engine for your dbt projects. Think of it as:
- A change detection system that actually understands data lineage
- A collaboration layer that speaks both engineer and stakeholder languages
- A safety net that catches what schema tests miss

💡 Why Top Data Teams Are Adopting Recce
The Visibility Advantage
- See beyond the schema: While dbt tests check constraints, Recce shows you actual value changes across environments
- Impact mapping: Visualize how a single column change ripples through 20 downstream models
- Checklist generation: Automates the "what should I review?" mental labor
Real-World Results
The Rio de Janeiro Department of Health saw:
- 90% reduction in PR review time
- 10x productivity boost
- Confidence in health records for 7 million people
As Thiago Trabach (Head of Data Science) put it: *"From a day to less than an hour to merge."*
🛠️ How Recce Works in Practice
1. Change Detection
Recce automatically:
- Identifies modified models and their dependencies
- Flags high-risk changes (like type conversions)
- Generates comparison queries
2. Contextual Validation
- Side-by-side data diffs (not just schema)
- Lineage visualization
- Sample record comparisons
3. Collaborative Review
- Shareable reports with business context
- SOC-2 compliant cloud option
- Stakeholder-friendly summaries
🌐 Where Recce Fits in Your Stack
Recce complements (rather than replaces) your existing tools:
| Tool | What It Does | Where Recce Adds Value | |--------------|-------------|------------------------| | dbt Core | Model transformation | Shows data impact of those transforms | | dbt Cloud CI | Runs tests | Provides visual change context | | Data Lineage | Shows flows | Highlights active impact areas |
🚀 Getting Started with Recce
For dbt Teams:
- Install via `pip install recce` (GitHub)
- Run `recce review` against your PR
- Share findings via Recce Cloud
Key Features to Explore:
- Automated checklists: Never miss a review step

Pro Tip: Start with their live demo to see Recce in action before installing.
🔮 The Future of Data Reviews
As data systems grow more complex, tools like Recce aren't just nice-to-have - they're becoming essential. What excites me most isn't just the time savings (though 90% is impressive), but how it changes team dynamics:
- Engineers spend less time firefighting
- Stakeholders gain trust through visibility
- Organizations ship faster without sacrificing quality
In an era where data quality makes or breaks companies, having this level of review confidence might soon be as standard as version control.
