Data reliability tool for profiling and testing your data

Data Reliability = Profiling + Testing
Piperider is a CLI tool that allows you to build data profiles and write assertion tests for easily evaluating and tracking your data's reliability over time.
Core Concepts
- Profile Your Data to explore/understand what kind of dataset you're dealing with e.g. completeness, duplicates, missing values, distributions
- Test Your Data to verify that your data is within acceptable range and formatted correctly
- Observe & Monitor Your Data to keep an eye on how that data changes over time
Key Features
- SQL-based (additionally supports CSV)
- Data Profiling Characteristics
- Provides rich data profiling metrics
- e.g.
missing,uniqueness,duplicate_rows,quantiles,histogram
- Test datasets with a mix of custom and built-in assertion definitions
- Auto-generates recommended assertions based on your single-run profiles
- Generates single-run reports to visualize your data profile and assertion test results (example)
- Generates comparison reports to visualize how your data has changed over time (example)
- Supported Datasources: Snowflake, BigQuery, Redshift, Postgres, SQLite, DuckDB, CSV, Parquet.
Quickstart
Installation
pip install piperider
By default, PipeRider supports built-in SQLite connector, extra connectors are available:
| connectors | install |
|---|---|
| snowflake | pip install 'piperider[snowflake]' |
| postgres | pip install 'piperider[postgres]' |
| bigquery | pip install 'piperider[bigquery]' |
| redshift | pip install 'piperider[redshift]' |
| parquet | pip install 'piperider[parquet]' |
| csv | pip install 'piperider[csv]' |
| duckdb | pip install 'piperider[duckdb]' |
Use comma to install multiple connectors in one line:
pip install 'piperider[postgres,snowflake]'
Initialize Project & Diagnose Settings
Once installed, initialize a new project with the following command.
piperider init # initializes project config
piperider diagnose # verifies your data source connection & project config
Profiling and Testing Your Data
Next, execute piperider run, which will do a number of things:
- Create a single-run profile of your data source
- Auto-generate recommended or template assertions files (first-run only)
- Test that single-run profile against any available assertions, including custom and/or recommended assertions
- Generate a static HTML report, which helps visualize the single-run profile and its assertion results.
Common Usages/Tips:
piperider run # profile all tables in the data source.
piperider run --table $TABLENAME # profile a specific table
piperider generate-report -o $PATHNAME # Specify the output location of the generated report
piperider generate-assertions # To re-generate the recommended assertions after the first-run
Comparing Your Data Profiles
With at least two runs completed, you can then run piperider compare-reports, which will generate a comparison report that presents the changes between them (e.g. schema changes, column renaming, distributions).
Common Usages/Tips:
piperider compare-reports --last # Compare the last two reports automatically using
For more details on the generated report, see the doc
