If the scheduler interval is faster than the processing of the flow, what should you do?

• A. Disable the scheduler.
• B. Set max concurrency in the flow to 1.
• C. Increase the scheduler interval.
• D. Enable a transaction per message.

Answer: (B)

When the trigger runs faster than the work the flow can complete, you get overlapping executions that can lead to race conditions or out-of-order processing. The way to fix this is to serialize processing so only one message is handled at a time. Setting the maximum concurrency for the flow to 1 enforces that serialization, making each trigger wait for the current message to finish before starting the next one. This aligns the trigger rate with what the flow can reliably process and helps maintain consistent behavior. Disabling the scheduler would stop automation entirely, which defeats the purpose. Increasing the scheduler interval reduces trigger frequency but doesn’t guarantee serialization if bursts occur or if several triggers queued up. Enabling a transaction per message affects rollback and integrity but doesn’t prevent parallel processing by the scheduler and flow, so it doesn’t address the root issue of concurrent executions.
