Hi,

I would like to insert in the same elasticsearch document, all jdbc rows with the same ID into a nested field called "logs".  
Can someone explain me how to convert jdbc input rows of logs into the following JSON structure :

`{ "id";"4dca1978-a591-4a6e-a431-1e9b0ee7a2e1", "logs":[{ "jdbcColumn1":"value1", "jdbcColumn2":"value2", "jdbcColumn3":"value3" },{ "jdbcColumn1":"value1", "jdbcColumn2":"value2", "jdbcColumn3":"value3" }] }`

Thank you!
