The Rename and Rename by Replacing Operators are powerful tools if you want to rename your attributes. At some point, however, not even these tools are enough. One example for this is to transform all attributes into lower case characters. You need this for some databases or hdfs. The solution for this is a very short groovy script which loops over all attributes and replaces them with the lower case version.
