SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MessyData enables you to generate synthetic, realistic dirty data for testing data pipelines, data quality tooling, and ML workflows without writing custom data generators.

Core Features & Use Cases

  • Declarative YAML config: define datasets, distributions, and anomalies without writing procedural code.
  • Date-aware generation and both CLI and Python APIs for end-to-end data generation workflows.
  • Use cases include validating pipelines, stress-testing anomaly detection, and simulating real-world data quality issues.

Quick Start

Create a MessyData YAML config, then run the validate command before generating.

FAQPage Schema
How do I generate realistic dirty data for testing data pipelines?

You can generate synthetic dirty data by defining a declarative YAML configuration that specifies datasets, distributions, and anomalies. This approach replaces custom procedural data generators and supports date-aware generation via CLI or Python API.

What is synthetic data anomaly injection and when do I need it?

Synthetic data anomaly injection is the process of deliberately introducing realistic errors into generated datasets. You need it when validating data quality tools or stress-testing anomaly detection algorithms against imperfect real-world data conditions.

How do I validate a YAML config before generating synthetic datasets?

To validate a YAML config before generating synthetic datasets, run the validate command against your configuration file. This ensures your declarative setup satisfies the required YAML schema and orchestration rules before executing data generation pipelines.

Can I use Python APIs for end-to-end synthetic data generation workflows?

Yes, you can use Python APIs for end-to-end synthetic data generation workflows. The framework provides both CLI and Python API interfaces, allowing you to programmatically control date-aware generation and anomaly injection within your testing scripts.

Does declarative YAML data generation support date-aware modes?

Yes, declarative YAML data generation supports date-aware modes. This feature allows you to generate synthetic dirty data with realistic temporal distributions, which is critical for accurately testing time-series pipelines and ML workflows.
