I am able to merge n number of files using MergeText processor but actually they are appending one after the other.
Is it feasible to join the data or merge two files on the basis of one common header. for eg. I have uuid column in one file with 5 different cols and the same column in other file with 6 more different col, can i join here both the files and get 12 cols dataset in output file(having one common comparison column).
We can treat this case as an equijoin condition.
Thanks in advance!
I have not tried this yet but look into Correlation Attribute Name in the mergecontent processor
