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

ThoughtSpot

  • Limited chart customization options; font, color, and size customizations for visualizations are restricted
  • Data modeling setup is complex and requires specialized expertise
  • High implementation costs restrict adoption for smaller organizations
  • Requires quality data and user training to fully realize benefits
