Xavier Léauté commented on KAFKA-5275:
--------------------------------------
Now that describe topic doesn't auto-create the topic anymore it's easier to
implement a "create topic if not exists" functionality that doesn't require
listing all topics. However given the nature of the async API, it still feels
cumbersome to write, e.g.
{code}
try {
adminClient.describeTopics(Collections.singleton(publishTopic)).all().get();
log.debug("Metrics reporter topic {} already exists", publishTopic);
} catch (ExecutionException e) {
if (!(e.getCause() instanceof UnknownTopicOrPartitionException)) {
// something bad happened
throw e;
}
// create logic here
}
{code}
> Review and potentially tweak AdminClient API for the initial release (KIP-117)
