Microsoft's Open Source PostgreSQL Extension Challenges MongoDB's Dominance

Microsoft's release of an open-source extension stack for PostgreSQL to handle document-style data is not only a challenge to MongoDB's NoSQL dominance but also blurs the lines between relational and non-relational databases. This move, from a company built on proprietary software, aims to attract developers with its lightweight approach. The extensions, pg_documentdb_core and pg_documentdb_api, support BSON and provide MongoDB-compatible commands. They work with FerretDB, an open-source MongoDB alternative. Experts see this as document databases becoming features within relational systems. MongoDB dismissed the move, while FerretDB sees it as an opportunity to build a stronger, collaborative foundation for MongoDB alternatives. The move highlights the evolving landscape of database technology and the increasing convergence of relational and NoSQL approaches.
