Using Python to create Greenplum 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 Greenplum.

If you want to set up a Greenplum environment for dev and test purposes, take a look at: https://dev.to/mesmacosta/quickly-set-up-a-greenplum-environment-on-gcp-2lkd

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 GREENPLUM_SERVER=127.0.0.1 export GREENPLUM_USERNAME=gpadmin export GREENPLUM_PASSWORD=gppassword export GREENPLUM_DATABASE=gpadmin python metadata_generator.py \ --greenplum-host=$GREENPLUM_SERVER \ --greenplum-user=$GREENPLUM_USERNAME \ --greenplum-pass=$GREENPLUM_PASSWORD \ --greenplum-database=$GREENPLUM_DATABASE 

And that's it!
