Re: Get request header from Kinesis


Could you point to the AWS Kinesis Java API that exposes record headers?
As far as I can tell from the Javadoc, I can’t seem to find how to retrieve headers from Kinesis records.

If there is a way to do that, then it might make sense to expose that from the Kinesis connector’s serialization / deserialization schema interfaces.

    I am using below code to read data from AWS Kinesis stream. But it is giving me the request body and not the request header. How to get the request header from Kinesis. My flink jar versions are:
flink-java - 1.6.1
flink-streaming-java_2.11 - 1.6.1
flink-connector-kinesis_2.11 - 1.6.1

My code is: 
Properties consumerConfig = new Properties();
consumerConfig.put(ConsumerConfigConstants.AWS_REGION, "<Region>");
consumerConfig.put(ConsumerConfigConstants.AWS_ACCESS_KEY_ID, "<KEY>");
consumerConfig.put(ConsumerConfigConstants.AWS_SECRET_ACCESS_KEY, "<SECRET>");
consumerConfig.put(ConsumerConfigConstants.STREAM_INITIAL_POSITION, "LATEST");
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
DataStream<String> kinesis = env.addSource(
new FlinkKinesisConsumer<String>("<STREAM>", new SimpleStringSchema(), consumerConfig));
kinesis.addSink(new SinkFunction<String>() {
public void invoke(String value) throws Exception {
System.out.println("value= "+value);
