------------------------------------------
Resolution: Won't Fix
> Configurable remote fetch bytes per partition from Consumer
> -----------------------------------------------------------
>
> Key: KAFKA-15777
> URL: https://issues.apache.org/jira/browse/KAFKA-15777
> Project: Kafka
> Issue Type: Task
> Reporter: Kamal Chandraprakash
> Assignee: Kamal Chandraprakash
> Priority: Major
> Labels: kip
>
> A consumer can configure the amount of local bytes to read from each
> partition in the FETCH request.
> {{max.fetch.bytes}} = 50 MB
> {{max.partition.fetch.bytes}} = 1 MB
> Similar to this, the consumer should be able to configure
> {{max.remote.partition.fetch.bytes}} = 4 MB.
> While handling the {{FETCH}} request, if we encounter a partition to read
> data from remote storage, then rest of the partitions in the request are
> ignored. Essentially, we are serving only 1 MB of remote data per FETCH
> request when all the partitions in the request are to be served from the
> remote storage.
> Providing one more configuration to the client help the user to tune the
> values depending on their storage plugin. The user might want to optimise the
> number of calls to remote storage vs amount of bytes returned back to the
> client in the FETCH response.
