AWS Step Functions now supports higher throughput workflows, making it easier to coordinate applications with high event rates and variable loads. Starting today, throughput has increased from 400 state transitions per second to 1,000 state transitions per second with burst capacity of 5,000 state transitions. The default start rate for AWS Step Functions state machine executions has also increased from 25 per second to 200 per second, with burst capacity of up to 1,000 starts in select regions.
