I have two different files one with CSV and one with XML  
Both has one common field and data has to be stored as a single set from both files  
To achieve that, I have now parsed and stored CSV first  
then while parsing XML I used "elastic-search-filter" plugin to query the data from previous log and added fields.  
Is there any way to do that without storing the CSV to elastic search first, in a way can I parse both log types and compare and combine fields in one go ?
