> Close `RecordBatch.records` when append to batch fails
> ------------------------------------------------------
>
> Key: KAFKA-3747
> URL: https://issues.apache.org/jira/browse/KAFKA-3747
> Project: Kafka
> Issue Type: Improvement
> Reporter: Ismael Juma
> Assignee: Ismael Juma
> Fix For: 0.10.0.1
>
>
> We should close the existing `RecordBatch.records` when we create a new
> `RecordBatch` for the `TopicPartition`.
> This would mean that we would only retain temporary resources like
> compression stream buffers for one `RecordBatch` per partition, which can
> have a significant impact when producers are dealing with slow brokers, see
> KAFKA-3704 for more details.
