>             Project: Flink
>          Issue Type: Improvement
>          Components: Connectors / Common
>    Affects Versions: 1.6.0
>            Reporter: Chesnay Schepler
>            Priority: Minor

> The {{StreamingFileSink}} uses the {{Encoder}} interface to serialize data.
> {code}
> public interface Encoder<IN> extends Serializable {
> 	void encode(IN element, OutputStream stream) throws IOException;
> }
> {code}
> The implementation (with the exception for strings) must be provided by the user.
> To use any {{OutputStream}} implementation that is a little more convenient than the base {{OutputStream}} (like {{DataOutputStream}}) requires creating a new stream for every single record. If an implementation is used that potentially buffers data users additionally have to call {{flush()}}.
> Instead we could allow specifying an optional factory for the streams, that would be called once for each part file, and modify the {{Encoder}} interface to have a generic type for the output stream.
