How It Works

Calculate optimal read/write replica ratios for CQRS architectures. Estimate read model scaling factors based on query-to-command ratios for high-performance systems

Each component has a specific meaning:

  • Query-to-command ratios — The query-to-command ratios recorded for the scenario being assessed.

Note: Interpret the cqrs scaling result against the thresholds and context described above.

How to Use

Enter the query-to-command ratios for the scenario you are assessing. Calculate optimal read/write replica ratios for CQRS architectures. Estimate read model scaling factors based on query-to-command ratios for high-performance systems. Use the cqrs scaling result to inform your calculation.
