FTP ingestion schedule
The ingest directory of the FTP account is processed every hour on the hour (e.g., 8:00, 9:00, 10:00, etc). If files are encountered, the modification time is checked. If the file has not been modified within the last fifteen minutes, then the file is processed. If the file has been modified within the last fifteen minutes, then it is ignored until the next scan.
Keep in mind that the file name dictates how the file is processed. If the file name does not adhere to the naming convention, then the file will fail to be ingested.
