AWS Lambda increases SQS event pollers to 10,000 in Provisioned Mode
AWS Lambda has increased the maximum number of event pollers for Amazon SQS event source mappings in Provisioned Mode from 2,000 to 10,000. This update allows for up to 100,000 concurrent invocations per mapping, significantly improving scalability for event-driven applications with high performance demands. Previously, the lower limit necessitated splitting workloads across multiple mappings. The feature is now generally available in all AWS commercial regions and can be configured via multiple AWS interfaces.

Enhancements (1) ›
- Increase max event pollers for SQS event source mappings
AWS Lambda now supports up to 10,000 event pollers for Provisioned Mode with Amazon SQS event source mappings, a fivefold increase from the previous limit of 2,000. This change enables up to 100,000 concurrent invocations per mapping, facilitating more scalable event-driven applications.
Notes (2) ›
- Enables higher throughput and reduced complexity for event-driven apps
The increased poller limit allows customers to handle more demanding workloads, such as real-time order processing and financial transactions, without needing to split them across multiple event source mappings. This simplifies architecture and improves responsiveness for mission-critical applications.
- Feature now generally available
Provisioned Mode for SQS ESM with the increased poller limit is generally available in all AWS commercial regions. Configuration options include the Lambda ESM API, AWS Console, AWS CLI, AWS SDK, AWS CloudFormation, and AWS SAM.
