In this blog, it is discussed how Lambda concurrency is determined when a SQS FIFO queue is configured as the trigger.

In this blog post, explains how a Lambda based Serverless application reacts to the errors and attempts to re-drive messages to the origin in a controlled manner.

This is another way of managing EventBridge Schedules withing Step Functions execution.

With the support of Step Function SDK integrations, we can manage EventBridge Schedules.
