I think reading up on Kafka. Going by KakfaIO as an example: there is a read() in kafkaIO, and we use this to do readFromKafka or readFromKafka -> KafkaIO.<String, String>read() readAvrosFromKafka -> KafkaIO.<String, String>read() I have also created a readStandardStream following the same chain of through. -- This is an automated message from the Apache Git Service.
