How often does Marketing Cloud Personalization poll the SFTP for new files for ingestion?

Marketing Cloud Personalization's ETL (Extract, Transform, Load) system automatically polls the configured SFTP directory for new data files at a fixed interval. The system is designed to check for new files to ingest every 15 minutes. Once a new file is detected, Personalization begins the process of importing and processing the data according to the feed's configuration. This regular, frequent polling ensures that user, catalog, and transactional data from external systems is updated in a timely manner.

A. The system polls at a set interval; it does not process files immediately upon upload.

C. The polling frequency is more rapid than hourly, allowing for quicker data synchronization.

D. A daily check would be too infrequent for most marketing personalization use cases that rely on timely data.
