> URL: https://issues.apache.org/jira/browse/APEXCORE-648
> Project: Apache Apex Core
> Issue Type: Bug
> Reporter: Vlad Rozov
> Assignee: Vlad Rozov
> Priority: Minor
>
> DefaultStatefulStreamCodec.toDataStatePair() calls Kryo Output.toBytes() that
> creates new byte[] and copies serialized data to the newly allocated array.
> It is not necessary as the output of toDataStatePair() will be copied again
> in PayloadTuple.getSerializedTuple().
