Where each one falls short

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

GitLab CI/CD

  • Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
  • Additional compute minutes beyond quota incur charges; exact pricing not specified

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
