Pierre-Yves Ritschard updated KAFKA-3006:
-----------------------------------------
Description:
The KafkaConsumer API has some annoying inconsistencies in the usage of
collection types. For example, subscribe() takes a list, but subscription()
returns a set. Similarly for assign() and assignment(). We also have pause() ,
seekToBeginning(), seekToEnd(), and resume() which annoyingly use a variable
argument array, which means you have to copy the result of assignment() to an
array if you want to pause all assigned partitions. We can solve these issues
by adding the following variants:
{code}
void subscribe(Collection<String> topics);
void subscribe(Collection<String> topics, ConsumerRebalanceListener);
void assign(Collection<TopicPartition> partitions);
void pause(Collection<TopicPartition> partitions);
void resume(Collection<TopicPartition> partitions);
void seekToBeginning(Collection<TopicPartition>);
void seekToEnd(Collection<TopicPartition>);
{code}
This issues supersedes KAFKA-2991
