How PGSimCity Turns PostgreSQL Complexity Into a Virtual City 3D Simulation
Nikolay Samokhvalov has developed PGSimCity, an open-source educational tool that visualises PostgreSQL mechanics as a 3D spatial simulation in the browser. It assists backend developers and site reliability engineers in understanding SQL and the dynamics of kernel execution. The project is available on GitHub and aims to enhance understanding of database architecture through interactive…
PGSimCity is an open-source educational visualization tool that transforms PostgreSQL cluster mechanics into an interactive 3D spatial simulation. The tool, released by Nikolay Samokhvalov, bridges the gap between high-level SQL queries and low-level kernel execution, making it accessible to backend developers, site reliability engineers, and database architects.
It achieves this by transforming PostgreSQL internals into explicit municipal districts, allowing users to observe and interact with various components such as the postmaster supervisor, worker processes, shared_buffers pool, wal_buffers, ProcArray, lock tables, Commit Log (CLOG), storage excavations, and Write-Ahead Logging.
