If I have logstash reading csv files, with fields in a particular order, and then I change the order in both the new csv files and the logstash config file, does logstash and/or elasticsearch care? If I also add new fields into the csv records, does logstash or elasticsearch care? In both cases, elasticsearch will have records with both the old and new order and fields. ---
