Developer Shares Why He Switched from Relational Databases to MongoDB

A software developer has shared his experience transitioning from relational databases like PostgreSQL to MongoDB after hitting scalability and flexibility limits. He found that managing schema migrations and horizontal scaling for write-heavy, globally distributed applications was consuming too much development time. MongoDB's document-based, flexible schema model allowed him to prototype faster and evolve his data structure alongside application code. He noted that MongoDB's built-in AI features and cost-effective infrastructure made it a better fit for modern application demands. The developer acknowledged that relational databases remain superior for complex multi-table joins, emphasizing that the choice should depend on the specific use case.
