I am aware that there is a 50k limit on classifications when uploading a file via the web site - does anybody know if there is a limit for files that are uploaded via ftp? I have hoping to upload somewhere between 400k and 500k rows.
FTP exists to upload larger data sets of files exceeding 50,000 rows which is the limitation of the Browser Import. We recommend to break large files into 50 MB chunks and upload since smaller files result in slow processing. Document for your reference : FTP Import
