Where each one falls short

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

Apache Flink

  • Genuinely difficult: event time, watermarks and state backends are a real conceptual load before anything works
  • Operationally heavy — job managers, task managers, checkpoint storage and state size are all yours to run and tune
  • State grows with the workload, and large state changes recovery time and cost significantly
  • Overkill where a scheduled batch job would answer the same question

Tyk

  • Professional and Enterprise plan pricing not published; contact required
  • Core plan uses consumption-based model with variable costs
  • No upfront pricing transparency for production deployments

Apache Flink: What is event-time processing?

Computing based on when an event actually occurred rather than when it arrived. It is what makes results correct when data is late or out of order, and it is the main reason Flink is harder than it looks.

All Tyk plans support Cloud, Hybrid, or Self-managed deployment options without feature restrictions, allowing flexible infrastructure choices across pricing tiers.
