--------------------------------------
Summary: Improve collection type consistency in KafkaConsumer API
Key: KAFKA-2991
URL: https://issues.apache.org/jira/browse/KAFKA-2991
Project: Kafka
Issue Type: Improvement
Reporter: Jason Gustafson
Assignee: Jason Gustafson
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()
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 assign(Collection<TopicPartition> partitions);
void pause(Collection<TopicPartition> partitions);
void resume(Collection<TopicPartition> partitions);
{code}
I'm not actually sure that there is any need for the generic Collection, so an
alternative would be to just use Set.
