Where each one falls short

  • 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

Geckoboard

  • Annual billing required; monthly billing not offered
  • Add-on dashboards cost $24 each
  • Additional editors cost $20 each
  • Additional screens cost $20 each
