Introducing pre-warming for Amazon Keyspaces tables

This article introduces the pre-warming feature for Amazon Keyspaces tables, enabling proactive throughput management to avoid cold start delays during traffic spikes.

• Pre-warming sets minimum warm throughput values tables handle instantly without dynamic scaling
• Default on-demand tables support 12,000 RCU and 4,000 WCU; pre-warming configurable up to 40,000 units
• Asynchronous process works with both on-demand and provisioned capacity modes
• Multi-Region deployments automatically propagate pre-warming settings across all regions
• Pricing based on one-time charge for difference between requested and current warm throughput
• IoT example: pre-warming to 40,000 WCU/RCU costs $27.04 one-time in us-east-1
• Integrates with existing IAM permissions and CloudWatch monitoring

Pre-warming enables Amazon Keyspaces tables to handle immediate high-throughput workloads during product launches or sales events, eliminating throttling and ensuring consistent sub-millisecond performance.
