dash-synthetic 0.1.5

Synthetic data generation for Databricks — with a built-in notebook UI

DashSynthetic — Databricks Library

Part of the Dashlibs suite — Databricks libraries built for business users.

Installation

%pip install dash-synthetic

Quick Start

import dashsynthetic
dashsynthetic.launch()   # Opens interactive UI in your Databricks notebook

The UI has two tabs:

• Single Table — profile a source table/DataFrame/SQL query and generate synthetic data from it.
• Multi-Table Relationships — define multiple tables, their primary keys, foreign keys, and master data columns (e.g. currency/country codes); the tool figures out the dependency order and generates every table with referentially valid foreign keys.

What it looks like

Single Table — profile a source and generate synthetic data from it:

Multi-Table Relationships — define tables, primary/foreign keys, and master data columns:

Python API

from dashsynthetic import RelationshipGraph, MultiTableGenerator

graph = RelationshipGraph()
graph.add_table("Customer", table="catalog.schema.dim_customer", primary_key="customer_id")
graph.add_table("Account", table="catalog.schema.fact_account", primary_key="account_id",
                master_data_columns=["currency_code"])
graph.add_foreign_key("Account", "customer_id", "Customer", "customer_id")

gen = MultiTableGenerator(graph)
gen.configure_table("Customer", n_rows=5000)
gen.configure_table("Account", n_rows=20000, output_table="catalog.schema.syn_account")
results = gen.run()   # {"Customer": df, "Account": df}, generated in dependency order

Quality & Contributing

• 16 unit tests, zero Spark dependency to run them — pytest tests/ -v (the relationship graph, generation ordering, and multi-table orchestration logic are all pure Python and fully covered)
• Lint-clean (ruff check dashsynthetic/), PEP 561 typed (py.typed)
• Every change ships through a reviewed pull request; CI (lint → test on Python 3.9–3.12 → build) gates every PR and every release
• See CONTRIBUTING.md for dev setup, CHANGELOG.md for release history, SECURITY.md to report a vulnerability, and CODE_OF_CONDUCT.md
