Ksolves India Limited commented on KAFKA-10059: ----------------------------------------------- [~bob-barrett] This ticket needs further elaboration on the issue. Additionally, include logs if this is causing any problems. Based on our analysis, changing the null value to OffsetAndMetadata(-1, Optional.empty(), metadata) would result in an IllegalArgumentException with the message "invalid negative offset." Therefore, this change is not necessary unless an exception is thrown with the current null value. > 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: > {code:java} > // Negative offset indicates that the group has no committed offset for this > partition > if (offset < 0) { > groupOffsetsListing.put(topicPartition, null); > } {code} > 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 (v8.20.10#820010)
