Configuration Purpose

BillingModeSummary.BillingMode property is used to control how you are charged for read and write throughput and how you manage capacity for DynamoDBs.

Command Use-cases

• Misconfiguration and outlier detection
• Quantification of DynamoDB tables that could throttle during traffic spikes
• Quantification of DynamoDB tables that could easily be backed-up.
• Quantification of DynamoDB tables that need promotion from provisioned to on-demand mode (PAY_PER_REQUEST) before backup could be done.

Tips

• The cost of DynamoDB tables configured with PROVISIONED billing mode is lower.
• DynamoDB tables configured with PROVISIONED billing mode may throw throttles during traffic spikes.
• PROVISIONED billing mode is better suited for applications with predictable and proven traffic size.
• Its better to configure DynamoDB tables with PAY_PER_REQUEST option when building new applications to prevent throttles.
