--------------------------------------
Resolution: Fixed
> Adjust ShareFetchRequest RPC to optimise fetching and acknowledgement
> ---------------------------------------------------------------------
>
> Key: KAFKA-18433
> URL: https://issues.apache.org/jira/browse/KAFKA-18433
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Andrew Schofield
> Assignee: Andrew Schofield
> Priority: Major
> Fix For: 4.1.0
>
>
> Change the RPC request to better align the consumer and broker processing for
> fetching and acknowledgement. Specifically:
> * Remove PartitionMaxBytes because for share fetching the broker has
> responsibility for which partitions are fetched as opposed to the consumer
> * Add BatchSize which gives the optimal number of records for batches of
> acquired records and acknowledgements.
> There will likely be a future round of optimisation to follow.
