问题 I am using logstash with input jdbc, and would like to embed one object inside another with aggregate. How can I use add recursive? Ie add an object inside another object? This would be an example: { "_index": "my-index", "_type": "test", "_id": "1", "_version": 1, "_score": 1, "_source": { "id": "1", "properties": { "nested_1": [ { "A": 0, "B": "true", "C": "PEREZ, MATIAS ROGELIO Y/O", "Nested_2": [ { "Z1": "true", "Z2": "99999" } }, { "A": 0, "B": "true", "C": "SALVADOR MATIAS ROMERO",
