You can e.g. assign different types to them (with the input plugin's `type` option) and then use conditionals to choose between different csv filters.

Yes I did it but if i am updating the same record it will impact my performance.

Oh, so you're actually talking about joining data from two CSVs? Then say so.

Logstash doesn't support such joining, so you either have to update documents multiple times or merge the CSVs before Logstash sees them.
