When uploading a Conduit file through the interface, in the Operations > Upload tab, there is a maximum file size restriction of 1 MB for all types of Conduit data files.
This restriction is designed to prevent performance issues or file locks, that can interfere with the Conduit scheduled tasks from picking up other jobs in a timely manner.
Users have the option to upload files smaller than 1 MB. If the file is larger, you will see a warning message with the recommendation to divide it into smaller files or upload the bigger file directly through the SFTP.
