Bart Vercammen updated KAFKA-5387:
----------------------------------
Component/s: producer
> [Kafka Producer] - expose cluster metadata
> ------------------------------------------
>
> Key: KAFKA-5387
> URL: https://issues.apache.org/jira/browse/KAFKA-5387
> Project: Kafka
> Issue Type: Improvement
> Components: producer
> Affects Versions: 0.10.2.1
> Reporter: Bart Vercammen
>
> Kafka producer has a method to expose the number of partitions for a specific
> topic.
> {noformat} public List<PartitionInfo> partitionsFor(String topic) {
> try {
> return waitOnMetadata(topic, null,
> maxBlockTimeMs).cluster.partitionsForTopic(topic);
> } catch (InterruptedException e) {
> throw new InterruptException(e);
> }
> }
> {noformat}
> Instead of only returning the number of available partitions for a topic, it
> would be nice that the entire cluster metadata is exposed to the caller.
> This way we can make use of the partitioners in a more dynamic way.
> Something like this maybe :
> {noformat}public Cluster clusterMetaData() {noformat}
> Or, maybe even better, have the possibility to provide a partitioner when
> producing data on kafka, instead of only a specific partition number or a
> globally configured partitioner-class.
> {noformat}
> public Future<RecordMetadata> send(ProducerRecord<K, V> record, Partitioner
> partitioner, Callback callback)
> {noformat}
> Any suggestions or comments?
