I'm currently fixing some issues in the consumer and I'll make the region a
required argument.

> Project: Flink
> Issue Type: Sub-task
> Components: Streaming Connectors
> Affects Versions: 1.0.0
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
>
> Opening a sub-task to implement data source consumer for Kinesis streaming
> connector (https://issues.apache.org/jira/browser/FLINK-3211).
> An example of the planned user API for Flink Kinesis Consumer:
> {code}
> Properties kinesisConfig = new Properties();
> config.put(KinesisConfigConstants.CONFIG_AWS_REGION, "us-east-1");
> config.put(KinesisConfigConstants.CONFIG_AWS_CREDENTIALS_PROVIDER_TYPE,
> "BASIC");
> config.put(
> KinesisConfigConstants.CONFIG_AWS_CREDENTIALS_PROVIDER_BASIC_ACCESSKEYID,
> "aws_access_key_id_here");
> config.put(
> KinesisConfigConstants.CONFIG_AWS_CREDENTIALS_PROVIDER_BASIC_SECRETKEY,
> "aws_secret_key_here");
> config.put(KinesisConfigConstants.CONFIG_STREAM_INIT_POSITION_TYPE,
> "LATEST"); // or TRIM_HORIZON
> DataStream<T> kinesisRecords = env.addSource(new FlinkKinesisConsumer<>(
> "kinesis_stream_name",
> new SimpleStringSchema(),
> kinesisConfig));
> {code}
