About
Built by Marios Pavlidis
I'm a database administrator working across SQL Server, Oracle, PostgreSQL, and MongoDB. I built mongodbplan.com to make MongoDB execution plans easier to read and investigate — and to help teams transitioning from relational databases by translating familiar SQL queries into the equivalent MongoDB Query Language.
More about my work →What this is
mongodbplan.com is an independent, browser-based toolkit for MongoDB. The execution plan analyzer turns dense explain() JSON into a visual plan tree with evidence-backed performance findings. The SQL to MongoDB converter maps SELECT, JOIN, GROUP BY, and other SQL constructs to the equivalent find() and aggregate() commands — useful when adopting MongoDB alongside or instead of a relational database.
