Unwieldy aggregation pipelines for complex analytical queries
7/10 HighMongoDB's aggregation framework becomes brittle and unmaintainable for complex analytical queries. Pipelines require hundreds of lines of transformations that break easily when document structure changes. Teams often export data to SQL databases or data warehouses to handle reporting that would be simple SQL joins, adding operational overhead.

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

The aggregation pipelines became so complex they were unmaintainable, query performance was 10x slower than equivalent SQL, and the team spent 3 months rewriting everything in PostgreSQL.
