Hello,

i would like to advise on how the file input node on ace does transfer of remote files using sftp.does it pick one file after another if the * is specified? or it will pick all files at once. I have an environment where i have implemented a file input node with remote sftp and sometimes files are processed quickly but some days I can see files are picked one by one. i have tried adding the instances but i am not seeing any improvement in performance can someone help me please.
