> Key: FLINK-3387
> URL: https://issues.apache.org/jira/browse/FLINK-3387
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.0.0
> Reporter: Stephan Ewen
> Assignee: Subhobrata Dey
>
> Currently, the {{byte[]}} to object conversion and vice versa is always done
> by creating new byte array streams and Data Input/Output streams. That is
> pretty wasteful, we can optimize this with Flink's own classes:
> - {{DataInputDeserializer}}
> - {{DataOutputSerializer}}
