             Summary: Create RouteCSV Processor
                 Key: NIFI-1161
                 URL: https://issues.apache.org/jira/browse/NIFI-1161
             Project: Apache NiFi
          Issue Type: Task
          Components: Extensions
            Reporter: Mark Payne


We have a RouteText processor built for 0.4.0. This is very powerful but a very 
common use case will be routing and grouping CSV data. This use case, we can 
make the configuration far easier by creating a RouteCSV Processor instead of 
requiring the user to enter complicated Regular Expressions.

For instance, rather than a Grouping Regular Expression, we should provide
a Grouping Fields property where the user can simply enter a comma-separated 
list of CSV fields (numeric or perhaps column header names?)

Also, rather than comparing user-defined rules against a line of text, the 
rules could be compared against a specific CSV field.
