Snowflake Data Test - Starter Project

Prerequisites

Python 3.8.* or later.

See installation instructions at: https://www.python.org/downloads/

Check you have python3 installed:

python3 --version

Dependencies and data

Creating a virtual environment

Ensure your pip (package manager) is up to date:

pip3 install --upgrade pip

To check your pip version run:

pip3 --version

Create the virtual environment in the root of the cloned project:

python3 -m venv .venv

Activating the newly created virtual environment

You always want your virtual environment to be active when working on this project.

source ./.venv/bin/activate

Installing Python requirements

This will install some of the packages you might find useful:

pip3 install -r ./requirements.txt

Generating the data

A data generator is included as part of the project in ./input_data_generator/main_data_generator.py This allows you to generate a configurable number of months of data. Although the technical test specification mentions 6 months of data, it's best to generate less than that initially to help improve the debugging process.

To run the data generator use:

python ./input_data_generator/main_data_generator.py

This should produce customers, products and transaction data under ./input_data/starter

Getting started

Please save Snowflake model code in snowflake and infrastructure code in infra folder.

Update this README as code evolves.
