Hi,  
I am trying Logstash csv filter to put csv data into elastic search. There is a chance that new csv fields will be added in future. I am looking for an option where by deafult the new fields are converted as integer.

Is there a way out. I am ok, if any plugin code is also to be written.  
Automatic columns will be created as I find now, but could not find a way how to add automatic conversion for the new columns.

Regards  
Paresh
