🚀 Why Misata?

Misata isn't just a random data generator. It's an intelligent engine that understands your business logic, relationships, and constraints. Whether you need 50 rows for unit tests or 10 million rows for load testing, Misata delivers statistically realistic data that looks and behaves like the real thing.

⚡ Quick Start

1. Install

pip install misata

2. Generate

Describe what you need in plain English. Misata handles the rest.

# Basic generation (Rule-based, instant)
misata generate --story "A SaaS platform with 50K users, monthly subscriptions, and a 20% churn rate in Q3"

# Intelligent generation (LLM-powered)
export GROQ_API_KEY=gsk_...
misata generate --story "E-commerce store with seasonal trends and customer segments" --use-llm

3. Result

Misata creates a relational schema, generates the data, and saves it to ./generated_data.

📋 Schema: SaaS_Platform
   Tables: 4 (users, subscriptions, payments, events)
   Relationships: 3
   Events: 1 (Churn Spike Q3)

🚀 Performance: 385,000 rows/second
💾 Data saved to: ./generated_data

🔄 Schema Introspection & Seeding

Already have a database? Misata can reverse-engineer your schema and seed it with realistic data.

# 1. Introspect your existing DB
misata schema --db-url postgresql://user:pass@localhost:5432/mydb --output schema.yaml

# 2. Seed it with 100K rows of realistic data
misata generate --config schema.yaml --db-url postgresql://... --db-truncate

📈 Reverse Engineering from Charts

Describe a chart, and Misata generates the underlying data to match it.

💻 Python API

Seamlessly integrate Misata into your test suites and CI/CD pipelines.

Standard Generation

from misata import DataSimulator
from misata.llm_parser import LLMSchemaGenerator

# 1. Design schema with AI
llm = LLMSchemaGenerator(provider="groq")
config = llm.generate_from_story(
    "Healthcare app with patients, doctors, and appointments"
)

# 2. Generate data
simulator = DataSimulator(config)
for table_name, df in simulator.generate_all():
    print(f"Generated {len(df)} rows for {table_name}")
    df.to_csv(f"{table_name}.csv", index=False)

SQLAlchemy Seeding (Powerful!)

Directly seed your SQLAlchemy models without writing factories.

from misata import seed_from_sqlalchemy_models
from myapp.models import Base, engine

# Automatically analyzes your models and foreign keys
report = seed_from_sqlalchemy_models(
    engine, 
    Base, 
    default_rows=10_000, 
    create=True, 
    smart_mode=True  # Infers realistic values from column names
)

print(f"Seeded {report.total_rows} rows in {report.duration_seconds}s")

🎯 Business Constraints

Define complex rules that simple random generators can't handle.

from misata import Constraint, Table

timesheets = Table(
    name="timesheets",
    row_count=10000,
    constraints=[
        Constraint(
            name="max_daily_hours",
            type="sum_limit",
            group_by=["employee_id", "date"],
            column="hours",
            value=8.0,
            action="redistribute"  # Automatically fixes violations
        )
    ]
)
