Hi,  
I'm working on a project that I need to import 2 csv files, rename/modify that entries and agregate that 2 files...  
For example, I have a "file1" that contains the columns : id, name, state  
And I have a "file2" with the column names: entry, operator, date

I want to modify the column "entry" to "id", and do a relation between the files..  
All this in logstash.conf

Can you help me?

If you can split "file2" into two files, one containing entry,operator and the other containing entry,date then you could do it using a couple of [translate](https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html) filters.
