brandboat opened a new pull request, #16618: URL: https://github.com/apache/kafka/pull/16618
related to https://issues.apache.org/jira/browse/KAFKA-17153, Java disallow lambdas to implement abstract classes, and hence there are many ugly impl of Gague in code base. Those bad looking code will spring up as we migrate more and more scala code to java. Hence, we should offer a variety to accept functional interface for java code. For example: ```java public final <T> Gauge<T> newGauge(String name, Supplier<T> metric) { return newGauge(name, new Gauge<T>() { @Override public T value() { return metric.get(); } }, Collections.emptyMap()); } ``` ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
