Code review for data in dbt

PipeRider automatically compares your data to highlight the difference in impacted downstream dbt models so you can merge your Pull Requests with confidence.

How it works:

• Easy to connect your datasource -> PipeRider leverages the connection profiles in your dbt project to connect to the data warehouse
• Generate profiling statistics of your models to get a high-level overview of your data
• Compare target branch changes with the main branch in a HTML report
• Post a quick summary of the data changes to your PR, so others can be confident too

Core concepts

• Easy to install: Leveraging dbt's configuration settings, PipeRider can be installed within 2 minutes
• Fast comparison: by collecting profiling statistics (e.g. uniqueness, averages, quantiles, histogram) and metric queries, comparing downstream data impact takes little time, speeding up your team's review time
• Valuable insights: various profiling statistics displayed in the HTML report give fast insights into your data

Quickstart

1. Install PipeRider

   pip install piperider[<connector>]
   

   You can find all supported data source connectors here.

2. Add PipeRider tag on your model: Go to your dbt project, and add the PipeRider tag on the model you want to profile.

   --models/staging/stg_customers.sql
   {{ config(
      tags=["piperider"]
   ) }}
   
   select ...
   

   and show the models would be run by piperider

    dbt list -s tag:piperider --resource-type model
   

3. Run PipeRider

   piperider run
   

To see the full quick start guide, please refer to PipeRider documentation

Features

• Model profiling: PipeRider can profile your dbt models and obtain information such as basic data composition, quantiles, histograms, text length, top categories, and more.
• Metric queries: PipeRider can integrate with dbt metrics and present the time-series data of metrics in the report.
• HTML report: PipeRider generates a static HTML report each time it runs, which can be viewed locally or shared.
• Report comparison: You can compare two previously generated reports or use a single command to compare the differences between the current branch and the main branch. The latter is designed specifically for code review scenarios. In our pull requests on GitHub, we not only want to know which files have been changed, but also the impact of these changes on the data. PipeRider can easily generate comparison reports with a single command to provide this information.
• CI integration: The key to CI is automation, and in the code review process, automating this workflow is even more meaningful. PipeRider can easily integrate into your CI process. When new commits are pushed to your PR branch, reports can be automatically generated to provide reviewers with more confidence in the changes made when reviewing.

Example Report Demo

We use the example project git-repo-analytics to demonstrate how to use piperider+dbt+duckdb to analyze dbt-core repository. Here is the generated result (daily update)
