> KafkaFuture is one of the oldest and most commonly used classes in our public APIs. We introduced the method {{toCompletionStage}} to reduce the gap from the modern async style. It works, but it could be better. We assumed users would use {{toCompletionStage}} to chain the pipeline, but we missed the users who prefer the blocking style in lambdas. Unfortunately, the blocking method {{get}} has checked exceptions in its signature.
> In short, this ticket introduces {{join}} to KafkaFuture. It could be a simple method with a default implementation, such as {{{}toCompletionStage().toCompletableFuture().join(){}}}.
