So, I tested the processor. It works OK.
But I've got a question.
In JSON it's easy - json structure will include both attribute name and
attribute value. in CSV - there will be only values on the output. Don't you
think it would be useful to add a header, or attribute with avro-like generated
schema? I agree that specified attributes will be in provided order, but if
regex is used - then user won't be able to relate a value to a name. The same
is about core attributes - since we add only existing not empty.
If we decide to add avro-like schema, we gonna have problems - attribute
names could be non Avro-safe.
