-------------------------------
Summary: Down-converted uncompressed batches should respect fetch offset
(was: Down-converted uncompressed batches should respect requested offset)
> Down-converted uncompressed batches should respect fetch offset
> ---------------------------------------------------------------
>
> Key: KAFKA-5360
> URL: https://issues.apache.org/jira/browse/KAFKA-5360
> Project: Kafka
> Issue Type: Bug
> Reporter: Ismael Juma
> Assignee: Ismael Juma
> Priority: Blocker
> Fix For: 0.11.0.0
>
>
> More specifically, V2 messages are always batched (whether compressed or not)
> while V0/V1 are only batched if they are compressed.
> Clients like librdkafka expect to receive messages from the requested offset
> when dealing with uncompressed V0/V1 messages. When converting from V2 to
> V0/1, we seem to be returning all the messages in the V2 batch instead of
> messages from the requested offset.
> Thanks to [~edenhill] for investigating this.
