----------------------------------
Summary: Iterate record sets before calling Log.append
Key: KAFKA-6559
URL: https://issues.apache.org/jira/browse/KAFKA-6559
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 1.0.0
Reporter: Todd Palino
Assignee: Todd Palino
If a Produce request contains multiple record sets for a single
topic-partition, it is better to iterate these before calling Log.append. This
is because append will process all the sets together, and therefore will need
to reassign offsets even if the offsets for an individual record set are
properly formed. By iterating the record sets before calling append, each set
can be considered on its own and potentially be appended without reassigning
offsets.
While the core Java producer client does not current operate this way, it is
permitted by the protocol and may be used by other clients that aggregate
multiple batches together to produce them.
