Optimize the execution of your scheduled flows and avoid hitting governor limits by specifying a custom batch size. Partition flow interviews into smaller batches ranging from 1 to 200 directly from the flow’s start element. Previously, scheduled flows processed interviews in default batch sizes of 200, which can exhaust resources in complex automations.
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions. The scheduled flows must be using a runtime version of 63.0 or later.
How: To configure a custom batch size, open the flow, and then open the Start element to select an object. Under Advanced Options, enter the maximum batch size.
