Do you mean to return the String `"null"` or `<code>null</code>`?
> Kinesis streaming producer

>
> Key: FLINK-3230
> URL: https://issues.apache.org/jira/browse/FLINK-3230
> Project: Flink
> Issue Type: Sub-task
> Components: Streaming Connectors
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Robert Metzger
>
> Add a FlinkKinesisProducer for the Flink Kinesis streaming connector. We will
> be using AWS SDK implementation for code consistency with the
> FlinkKinesisConsumer.
> The features of FlinkKinesisProducer is rather straightforward:
> 1. Partition put records based on partition key.
> 2. Configurable put mode: Bulk put for higher throughput vs. sequential
> single record puts. Size of bulk should also be configurable.
> 3. For bulk put, user can also choose to enforce strict ordering of the
> result with the tradeoff of higher put latency. Ref:
> https://brandur.org/kinesis-order
