The short version

  • Each has a real cost: Go no built-in generic types until recent versions, requiring workarounds for type-safe collections; Prometheus not suitable for per-request billing as collected data lacks 100% accuracy
  • They diverge on capability: Go covers Goroutines, Prometheus covers Multi-dimensional Data Model.

Where each one falls short

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

Go

  • No built-in generic types until recent versions, requiring workarounds for type-safe collections
  • Error handling through explicit return values considered verbose compared to exception-based approaches
  • Smaller standard library compared to Python or Java; requires external packages for common tasks
  • Package management can create version conflicts and dependency hell issues

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection
