         In order to reduce storage overhead and improve API usability, a new method in the Java and Scala APIs that accepts a BiFunction for foreign key extraction is introduced by

+        <a href="https://cwiki.apache.org/confluence/x/gIuMEw">KIP-1104</a>.
         KIP-1104 allows foreign key extraction from both the key and value in KTable joins in Apache Kafka.
         Previously, foreign key joins in KTables only allowed extraction from the value, which led to data duplication and potential inconsistencies.
         This enhancement introduces a new method in the Java and Scala APIs that accepts a BiFunction for foreign key extraction, enabling more intuitive and efficient joins.
