Targeted at scenarios like product launches and seasonal events, pre-warming lets users specify expected peak throughput when creating or updating tables in provisioned or on-demand modes. This ensures immediate readiness to meet traffic spikes without experiencing scaling-induced errors or latency.
The process runs asynchronously and does not disrupt ongoing operations, with charges applied for the incremental resources reserved. This feature applies to multi-region replicated tables and is available in all commercial and GovCloud AWS regions supporting Keyspaces. Independent performance data was not provided in the announcement.
