AWS Lambda Provisioned Mode for SQS Event-Source Mappings
🔔 AWS Lambda now offers Provisioned Mode for SQS event-source mappings (ESMs), letting you provision persistent event pollers to handle sudden traffic spikes. Provisioned ESMs scale up to 3x faster (up to 1,000 concurrent executions/min) and support up to 16x higher concurrency (up to 20,000 concurrent executions), reducing latency for bursty workloads. The feature is generally available in all AWS Commercial Regions and is configurable via the Console, API, CLI, SDK, CloudFormation, and SAM; billing is by Event Poller Units (EPU).
