Charles Crain created KAFKA-7714: ------------------------------------ Summary: Scala streams API should use Options in left and outer joins Key: KAFKA-7714 URL: https://issues.apache.org/jira/browse/KAFKA-7714 Project: Kafka Issue Type: Improvement Components: streams Affects Versions: 2.1.0, 2.0.1 Reporter: Charles Crain
The Scala streams DSL for left and outer joins should use Options instead of possibly-null parameters to the joiner functions. As currently written, implementers of joiners for Kafka Streams must account for the right side of a left join (or either side of an outer join) being null, which is not idiomatic Scala. Note to reviewer: I would like to contribute this change myself. What is the policy on breaking API changes? Would it be acceptable to change the left/outer join APIs to accept options? Or would I need to implement parallel versions (naming suggestions if so?). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
