> I wonder why it was dropped starting from v1. Was it missed during a refactoring (e.g. when batching was introduced)? From what I see in the history it was indeed dropped when group batching was introduced with the implementation of KIP-709, mainly because with that we split the handling to read from zk vs read offsets from the internal topic (that made the difference) With the split handling introduced in that PR, v0 reads offsets from zk and throws UNKNOWN_TOPIC_OR_PARTITION if not found. And v1+ reads offsets from the internal topic, and the GC returns no error + offsets -1 if not found. This func introduced for KIP-709 https://github.com/apache/kafka/pull/10962/changes#diff-cc056b4960ededba37a438b1454f0f3c5ff5e8ad5e6d2ec9a08e813ca056ffebR1316 -- This is an automated message from the Apache Git Service.
