Bob Barrett updated KAFKA-10059: -------------------------------- Description: When listing consumer group offsets through the admin client, the map that we return has a null `OffsetAndMetadata` value if the partition has no committed offset: ```// Negative offset indicates that the group has no committed offset for this partition if (offset < 0) { groupOffsetsListing.put(topicPartition, null); } ``` It would be better to return a non-null value that indicates the lack of an offset, such as `OffsetAndMetadata(-1, Optional.empty(), metadata)`. was: When listing consumer group offsets through the admin client, the map that we return has a null `OffsetAndMetadata` value if the partition has no committed offset: It would be better to return a non-null value that indicates the lack of an offset, such as `OffsetAndMetadata(-1, Optional.empty(), metadata)`. > KafkaAdminClient returns null OffsetAndMetadata value when there is no > committed offset for a partition > ------------------------------------------------------------------------------------------------------- > > Key: KAFKA-10059 > URL: https://issues.apache.org/jira/browse/KAFKA-10059 > Project: Kafka > Issue Type: Improvement > Reporter: Bob Barrett > Priority: Minor > > When listing consumer group offsets through the admin client, the map that we > return has a null `OffsetAndMetadata` value if the partition has no committed > offset: > ```// Negative offset indicates that the group has no committed offset for > this partition > if (offset < 0) { > groupOffsetsListing.put(topicPartition, null); > } > ``` > It would be better to return a non-null value that indicates the lack of an > offset, such as `OffsetAndMetadata(-1, Optional.empty(), metadata)`. -- This message was sent by Atlassian Jira (v8.3.4#803005)
