join field

Idea created by LucasKaim on Mar 22, 2016
    Join field is very slow. One of the reasons that Join Field is slow is because that Join Field copies features into a new output. It should ultimately be up to the end user to decide if they want to make a copy of the data or append the data to the file they already have. After all a copy feature is not required to do an inner join. By allowing the user to append fields to an input file this will significantly speed up a join. If performance is an issue, then do not use join field, but instead use a search cursor and then an update cursor with either a dictionary or a generator. This tool: will work and appends fields instead of creating a new output.
