How to evaluate throughput utilization for Amazon DynamoDB tables in provisioned mode

Database Blog

This article provides a comprehensive guide to evaluating throughput utilization for Amazon DynamoDB tables in provisioned mode, helping users determine whether to switch to on-demand mode.

  • Throughput utilization measures consumed capacity relative to provisioned capacity
  • Uses Amazon CloudWatch metrics to calculate utilization percentage
  • Recommended switching to on-demand mode when utilization is below 30%
  • Utilization between 30-45% can still benefit from on-demand mode
  • Consider total cost of ownership beyond just throughput metrics

The article provides step-by-step instructions for plotting throughput utilization in CloudWatch and offers guidance on interpreting the results to optimize DynamoDB table performance and cost.
