Where each one falls short

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

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
  • Minimum commitment recommended for cost optimization

Rust

  • Compile times significantly longer than languages like Go or C
  • Smaller ecosystem of libraries and frameworks compared to Python or JavaScript
