When outputting to files in avro format, it would be nice to have Alteryx either throw an error/warning or automatically add a prefix when field names do not conform to the Apache Avro specifications. For example, if I were to try to output an .avro file with a field named "2018 actions", Alteryx could throw a warning/error to remind me to rename the field, or Alteryx could change the field name for me to something like "X2018_Actions".
