KAFKA-3007: implement max.poll.records (KIP-41)
----
> Implement max.poll.records for new consumer (KIP-41)
> ----------------------------------------------------
>
> Key: KAFKA-3007
> URL: https://issues.apache.org/jira/browse/KAFKA-3007
> Project: Kafka
> Issue Type: Improvement
> Components: consumer
> Affects Versions: 0.9.0.0
> Reporter: aarti gupta
> Assignee: Jason Gustafson
>
> Currently, the consumer.poll(timeout)
> returns all messages that have not been acked since the last fetch
> The only way to process a single message, is to throw away all but the first
> message in the list
> This would mean we are required to fetch all messages into memory, and this
> coupled with the client being not thread-safe, (i.e. we cannot use a
> different thread to ack messages, makes it hard to consume messages when the
> order of message arrival is important, and a large number of messages are
> pending to be consumed)
