Guozhang Wang created KAFKA-8584:
------------------------------------
Summary: Allow "bytes" type to generated a ByteBuffer rather than
byte arrays
Key: KAFKA-8584
URL: https://issues.apache.org/jira/browse/KAFKA-8584
Project: Kafka
Issue Type: Sub-task
Reporter: Guozhang Wang
Right now in the RPC definition, type {{bytes}} would be translated into
{{byte[]}} in generated Java code. However, for some requests like
ProduceRequest#partitionData, the underlying type would better be a ByteBuffer
rather than a byte array.
One proposal is to add an additional boolean tag {{useByteBuffer}} for
{{bytes}} type, which by default is false; when set to {{true}} set the
corresponding field to generate {{ByteBuffer}} instead of {{[]byte}}.
