KIP-367 Introduce close(Duration) to Producer and AdminClient instead of close(long, TimeUnit)

This page is meant as a template for writing a KIP. To create a KIP choose Tools->Copy on this page and modify with your content and replace the heading with the next KIP number and a description of your issue. Replace anything in italics with your own description.

KIP-266 have replaced the (long, TimeUnit) by Duration for KafkaConsumer. For consistency, we should do the same APIs migration for KafkaProducer and KafkaAdminClient. 

Public Interfaces

KafkaProducer

@Deprecated
@Override
public void close(long timeout, TimeUnit timeUnit) {
    close(timeout, timeUnit, false);
}


@Override
public void close(Duration timeout) {
    close(timeout.toMillis(), TimeUnit.MILLISECONDS, false);
}

Producer

@Deprecated
void close(long timeout, TimeUnit unit);


void close(Duration timeout);

...

@Override
public void close(Duration timeout) {


@Deprecated
public void close(long duration, TimeUnit unit)

Noted: the implementation of close(long, TimeUnit) will be placed at AdminClient.

AdminClient

@Deprecated
public void close(long duration, TimeUnit unit) {
    close(Duration.ofMillis(unit.toMillis(duration)));
}


public abstract void close(Duration timeout);

Noted: there is a default implementation of close(long, TimeUnit).

Proposed Changes

New Public methods are proposed. see Public Interfaces

In short, this KIP is going to deprecate close(long, TimeUnit) of KafkaProducer and KafkaAdminClient and add a replacement method - close(Duration)
