Extension Analyzer

This repository contains the code used to analyze the extension ecosystems of PostgreSQL, MySQL/MariaDB, SQLite, Redis, and DuckDB. The code for each of these systems and the instructions on how to run the analysis scripts can be found in their respective directories, except the PostgreSQL index-type analysis, which is included as a submodule.

Additionally, we have included our the CSVs used to run our plot scripts and the plot scripts themselves in the plot_scripts directory.

Feel free to submit PRs and offer feedback, we would love to hear it!
