> Key: FLINK-3387

> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.0.0

> 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:
> - {{DataInputSerializer}}
> - {{DataOutputSerializer}}
