Data Product SDK

Turn an ODCS data contract plus a set of pure transforms into a running, quality-gated, multi-target data product. One codebase runs on DuckDB locally and Databricks/Spark in production, behind a ports/adapters seam, with a Write-Audit-Publish quality gate derived entirely from the contract.

Proprietary software. This package is not open source. Installing it grants you the right to use it; it does not grant the right to redistribute it or to create derivative works. See the LICENSE file inside the distribution for the full terms.

Install

pip install dataproduct-sdk                 # DuckDB target (default)
pip install "dataproduct-sdk[databricks]"   # + the Databricks/Spark production target
pip install "dataproduct-sdk[api]"          # + serve a published port as a REST endpoint

Requires Python 3.12+.

Scaffold a product

dataproduct init            # interview -> a complete, green product repo
cd <your-product>
dataproduct check           # the fitness-function battery
dataproduct run             # transform -> audit -> publish

What a product looks like

# product.py
from dataproduct import Product
import transforms as T

product = Product(name="orders", domain="sales")

@product.table("orders")
def orders(src):
    return T.build_orders(src.read("orders_raw"))

@product.view("public_orders", reads=["orders"])
def public_orders(orders):
    return T.build_public_orders(orders)

product.enable_observability()

You write three things: transformation logic (pure ibis expression-to-expression functions), declared constraints (an ODCS contract), and topology (which output ports exist and what feeds them). The SDK supplies everything else.

What the SDK does for you

CLI

dataproduct init | run | serve | audit | docs | check
             quarantine | observability | evolve | generate
             explain | contract draft

Add --format json to explain and run --dry-run for machine-readable output.

Extending it

Targets are resolved through the dataproduct.adapters entry-point group, so a new backend is a separate distribution — no fork and no change to this package. The core depends only on the Protocols in dataproduct.ports.
