pick function

pick() will only include the specified fields from the message when sending down the pipeline. It currently only works for top level fields (i.e. address.street would not work).

configuration

pick({"fields": ["name"]})

example

message in

{
    "_id": 0,
    "name": "transporter",
    "type": "function"
}

config

pick({"fields":["_id", "name"]})

message out

{
    "_id": 0,
    "name": "transporter"
}
