Giovanni Bricconi created SOLR-3429:
---------------------------------------

             Summary: new GatherTransformer
                 Key: SOLR-3429
                 URL: https://issues.apache.org/jira/browse/SOLR-3429
             Project: Solr
          Issue Type: New Feature
          Components: contrib - DataImportHandler
    Affects Versions: 4.0
            Reporter: Giovanni Bricconi
            Priority: Minor


This is a new transformer for dih.
I'm often asked to import a lot of fields, many of these fields are read only and sould not
be searched.
I found useful to gather them in a single json field, and returning them untouched to the
client.

This patch provides a transformer that collects a list of db columns an writes out a json
map that contains all of them.

A regression test is included. 

A new dependency for jsonic has been added to dih, (already used by langid), I can use a different
library if needed.
