AWS Lambda announces Provisioned Mode for SQS event source mapping (ESM)

AWS Lambda announces Provisioned Mode for SQS event-source-mappings (ESMs) that subscribe to Amazon SQS, a feature that allows you to optimize the throughput of your SQS ESM by provisioning event polling resources that remain ready to handle sudden spikes in traffic. SQS ESM configured with Provisioned Mode scales 3x faster (up to 1000 concurrent executions per minute) and supports 16x higher concurrency (up to 20,000 concurrent executions) than default SQS ESM capability. This allows you to build highly responsive and scalable event-driven applications with stringent performance requirements.

Customers use SQS as an event source for Lambda functions to build mission-critical applications using Lambda's fully-managed SQS ESM, which automatically scales polling resources in response to events. However, for applications that need to handle unpredictable bursts of traffic, lack of control over the throughput of ESM can lead to delays in event processing. Provisioned Mode for SQS ESM allows you to fine tune the throughput of the ESM by provisioning a minimum and maximum number of polling resources called event pollers that are ready to handle sudden spikes in traffic. With this feature, you can process events with lower latency, handle sudden traffic spikes more effectively, and maintain precise control over your event processing resources.

This feature is generally available in all AWS Commercial Regions. You can activate Provisioned Mode for SQS ESM by configuring a minimum and maximum number of event pollers in the ESM API, AWS Console, AWS CLI, AWS SDK, AWS CloudFormation, and AWS SAM. You pay for the usage of event pollers, along a billing unit called Event Poller Unit (EPU). To learn more, read Lambda ESM documentation and AWS Lambda pricing.
