> Avoid double copying in the Kafka spout
> ---------------------------------------
>
> Key: STORM-1220
> URL: https://issues.apache.org/jira/browse/STORM-1220
> Project: Apache Storm
> Issue Type: Bug
> Reporter: Haohui Mai

>
> 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.
