> Today, we have good support for reading standalone JSON data.  However, sometimes (especially when reading from streaming sources such as Kafka) the JSON is embedded in an envelope that has other information we'd like to preserve.  It would be nice if we could also parse JSON string columns, while preserving the original JSON schema.
