Hi Gordon
This is the function snippet i am using but i am getting invalid
timestamp
Properties properties = new Properties();
properties.setProperty("bootstrap.servers", "localhost:9092");
properties.setProperty("group.id", "word");
properties.setProperty("auto.offset.reset", "earliest");
DataStream < WordCount > stream = env.fromElements(wordCount);
stream.assignTimestampsAndWatermarks(new
AscendingTimestampExtractor<WordCount>() {
@Override
public long extractAscendingTimestamp(WordCount element) {
return DateTime.now().getMillis();
}
});
FlinkKafkaProducer010.FlinkKafkaProducer010Configuration
config = FlinkKafkaProducer010.writeToKafkaWithTimestamps(stream,
KAFKA_TOPIC, new WordCountSchema(), properties);
config.setWriteTimestampToKafka(true);
env.execute(*"*job*"*);
