Amazon DynamoDB now supports a new warm throughput value and the ability to easily pre-warm DynamoDB tables and indexes. The warm throughput value provides visibility into the number of read and write operations your DynamoDB tables can readily handle, while pre-warming let’s you proactively increase the value to meet future traffic demands.
DynamoDB automatically scales to support workloads of virtually any size. However, when you have peak events like product launches or shopping events, request rates can surge 10x or even 100x in a short period of time. You can now check your tables’ warm throughput value to assess if your table can handle large traffic spikes for peak events. If you expect an upcoming peak event to exceed the current warm throughput value for a given table, you can pre-warm that table in advance of the peak event to ensure it scales instantly to meet demand.
Warm throughput values are available for all provisioned and on-demand tables and indexes at no cost. Pre-warming your table’s throughput incurs a charge. See Amazon DynamoDB Pricing page for pricing details. This capability is now available in all AWS commercial Regions. See the Developer Guide to learn more.
