Put output in a sub field from JDBC input

This is just a feature request sort of thing.

I would like to put all the data I pull from the JDBC input inside a subfield with a configurable name.

Something like:


input {
   jdbc {
      jdbc_output_field => "my_data"

So that the output looks like:

     "_index": "my_index-2016.08.31",
     "_type": "foo",
     "_id": "abc123",
     "_score": 1,
     "_source": { 
        "my_data": {
              "field_one_from_db": 1,
              "field_two_from_db": 2
       "some_field_i_add": "foo",
       "structure": {
          "more_things": "bar"

What do you think?

Doesn't sound unreasonable and it looks like it would be a trivial change. Feel free to file a feature request: https://github.com/logstash-plugins/logstash-input-jdbc/issues/new
