---------------------------------
Labels: needs-kip (was: )
> Kafka Connect. Add map entry value extraction SMT
> -------------------------------------------------
>
> Key: KAFKA-9318
> URL: https://issues.apache.org/jira/browse/KAFKA-9318
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 2.4.0
> Reporter: Piotr Smolinski
> Priority: Major
> Labels: needs-kip
>
> 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.
