             Summary: Provide a method to fetch committed offsets for a 
collection of TopicPartition
                 Key: KAFKA-8606
                 URL: https://issues.apache.org/jira/browse/KAFKA-8606
             Project: Kafka
          Issue Type: Improvement
          Components: clients, consumer
    Affects Versions: 2.2.1, 2.3.0
            Reporter: ov7a


Currently KafkaConsumer has methods for fetching begging offsets, end offsets 
and offsets for times, all of them accepting a collection of TopicPartition.

There is a method to fetch committed offset for single TopicPartition, but 
there is no public API to fetch commited offsets for a collection of 
TopicPartition. So, If one wants to fetch all committed offsets for topic, a 
request per partition is created.

Note that ConsumerCoordinator.fetchCommittedOffsets which called internally in 
"committed" method does accept a collection of TopicPartition.
