How is the ' id ' column of input data processed?

[hzrt123]

In Titanic and Iris examples, the input data has an 'id' column.

Then the dataframe goes through transmogrify() and sanityCheck(), and then train(), score().

I wonder how this 'id' column is dealt with ? Is it dropped somewhere in the trainning, or treated as a normal feature ?

Unless it’s explicitly extracted and passed into setResultFeatures on the workflow - it’s not being used.
