Jiangjie Qin commented on KAFKA-3664: ------------------------------------- [~hachikuji] That sounds reasonable. That is a what I am currently doing as a workaround, i.e. committing the offset manually before unsubscribe. As long as we document it clearly it should be fine. > When subscription set changes on new consumer, the partitions may be removed > without offset being committed. > ------------------------------------------------------------------------------------------------------------ > > Key: KAFKA-3664 > URL: https://issues.apache.org/jira/browse/KAFKA-3664 > Project: Kafka > Issue Type: Bug > Reporter: Jiangjie Qin > Assignee: Vahid Hashemian > > When users are using group management, if they call consumer.subscribe() to > change the subscription, the removed subscriptions will be immediately > removed and their offset will not be commit. Also the revoked partitions > passed to the ConsumerRebalanceListener.onPartitionsRevoked() will not > include those partitions. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
