We have nifi flows like below ListSFTP >> ... >> FetchSFTP >> ... >> MergeContent >> ... >> PutFTP - FetchSFTP fetch all files in yyyymmdd folder( ex : ./A1/20191018 ) one by one - MergeContent make all files into one zipfile. It works well, but fetching all files one by one takes long time. also it needs lots of memory. Therefore we want to change above process into below step1) Compress all files of one folder( ex : ./A1/20191018 --> 20191018.zip ) step2) Fetch this one zipfile step3) PutFTP In this process, I dont know about step1 How can I Compress all files in folder?
