> Currently there is ExtractField SMT available that makes it possible to pull specific field from generic JSON or Connect Struct. When Connect Struct with a map field is used this approach does not work when given map entry has to be extracted.
> Example case: JMS source imports message that has entity correlation key inside message property. We want to use the same key for Kafka messages.
> Currently it requires custom SMT coding, while the logic is generic.
