Changing the file creation limits
This content applies only to On-premises and Client-managed cloud environments
Control the size and number of files generated as a result of exporting interactions and decisions by changing the snapshot management settings of the WriteDataToInteractionFiles and WriteDataToDecisionFiles real-time data flow runs. By default, the runs create a file every 300 seconds or after processing 75,000 records, whichever comes first.
For more information about data flow runs, see Creating a real-time run for data flows.
