What are the disadvantages of MongoDB?

Written by Editorial Team | Last Updated: August 2026

MongoDB is a popular NoSQL document database, but it possesses notable disadvantages for certain application architectures. A primary drawback is its lack of traditional ACID transaction guarantees across multiple documents by default, which can complicate data consistency requirements for complex financial or relational operations. MongoDB's denormalized data model can also lead to significant data duplication, increasing storage overhead and requiring careful index management to maintain query performance. Furthermore, executing complex analytical queries, multi-table joins, or aggregations can be significantly slower and more resource-intensive compared to structured relational database management systems like PostgreSQL.
