Generates a demo datasource for SingleStore

SingleStore-demo - S2Generate

Generation of a simple datasource for SingleStore

This python script creates a database and fills it up with data to perform several types of testing on a SingleStore DB.

• Easy to use. Using pip to install
• Fast. Creates the database and data with several K of data in a couple minutes.

Features

• Can change the number of records to be inserted.
• Can change the database schema. Limited.

Tech

SingleStore-demo uses a number of open source projects to work properly:

• [Python] - HTML enhanced for web apps!
• singlestoredb-python - SingleStore DB Python connector.
• numpy - NumPy is the fundamental package for scientific computing with Python.
• mimesis - Mimesis is a high-performance fake data generator for Python

And of course SingleStore-demo itself is open source s2generator on GitHub.

Installation

SingleStore-demo requires Python v3.10+ and Pip v22.0+ to run.

Check the current version of installed Python and Pip by running:

$ python3 -V
Python 3.10.6
$ pip -V
pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

To install the script you need to run Pip, all the dependencies will be installed using a single command.

$ pip install singlestore-demo
