ETL - Ovewrite existing values & ignore position

[mchambre]

Hello,

I am configuring an ETL job as usual.

My customer tells me that he would like to have the ability to modify their data afterwards in the CSV (So without going into ETL, and reset positions)

I checked "Allow existing values to be overwritten", but it only works if I reset positions.

Is there a parameter or a procedure to ignore positions ?

Is there a risk of performance degradation during job execution ?

Thanks,

Regards,
