Is there a feeder transformation mechanism available?

I want my .csv file to contain column headers “firstName” and “lastName”.
I want those columns mapped to FIRST_NAME and LAST_NAME in the session.

Is there any easy transformation step built in to Gatling anywhere that would let me do that transformation, or will I have to do it manually?

No, we don’t have to built-in for renaming the columns. What you can do is copy the RecordSeqFeederBuilder and map the records in order to change the keys. Not sure it’s worth the effort…

That’s okay, I have a way. I just wanted to know if there was a feeder transformation hook or not.
