Using Python to create MySQL tables with random schema

Having a large amount of test data sometimes take a lot of effort, and to simulate a more realistic scenario, it’s good to have a large number of tables with distinct column types. This script generates random tables schema for MySQL.

Environment

Activate your virtualenv

pip install --upgrade virtualenv
python3 -m virtualenv --python python3 env
source ./env/bin/activate

Install the requirements for the metadata generator

pip install -r requirements.txt

Code

Execution

export MYSQL_SERVER=127.0.0.1
export MYSQL_USERNAME=test_user
export MYSQL_PASSWORD=test_user_pwd
export MYSQL_DATABASE=test_db

python metadata_generator.py \
--mysql_host=$MYSQL_SERVER \
--mysql_user=$MYSQL_USERNAME \
--mysql_pass=$MYSQL_PASSWORD \
--mysql_database=$MYSQL_DATABASE

And that's it!
