Hello guys! I'm new to this forum and to NiFi as well.
I'm trying to connect to an external FTP site, using ListFTP and FetchFTP processors on NiFi. The ListFTP object puts all files in a queue very fast, but the FetchFTP processor takes a lot of time to download the files, even using 5 threads on the FetchFTP it downloads 5 files and stand still for 30 seconds before starting the downloads again.
I've tried to download the same files via an external app, like Filezilla and the downloads are made in seconds.
Is there anything I can do to speed up this process?
I've tried using the GetFTP processor and it worked as fast as FileZilla. It seems that FetchFTP has some Polling Interval that isn't changeable by property.
