Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

MongoDB

  • 16 MB maximum document size limits large single objects
  • No native JOIN support for relational data operations
  • Higher memory usage due to storing field names with each document
  • Eventual consistency in distributed deployments can cause data stale reads
