--------------------------------------
Summary: 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
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.
