Limited join capabilities causing data duplication

7/10 High

MongoDB's document-oriented model lacks complex join support compared to SQL databases. The $lookup operator provides only basic functionality, forcing developers to redesign data models and embed related data within documents, which results in significant data duplication and storage overhead.

Query: “What are the most common pain points with MongoDB for developers in 2025?”4/4/2026
