> Currently the kafka spout takes a {{ByteBuffer}} from Kafka. However, the serialization scheme takes a {{byte[]}} array as input. Therefore the current implementation copies the {{ByteBuffer}} to a new {{byte[]}} array in order to hook everything together.
> This jira proposes to changes the interfaces of serialization scheme to avoid copying the data twice in the spout.
