Is there a way to do this that preserves exactly once semantics for the

How about writing to a buffer ? Then you would flush the buffer to Kafka if and
only if the output operation reports successful completion. In the event of a
worker failure, that would not happen.

after having applied several transformations to a DStream I'd like to

way to do that would be? Just using DStream.foreach and then RDD.foreach ?
Is there any other built in utility for this use case?
Thanks a
I'd be interested in finding the answer too. Right now, I do:
val kafkaOutMsgs = kafkInMessages.map(x=myFunc(x._2,someParam))
kafkaOutMsgs.foreachRDD((rdd,time) = { rdd.foreach(rec = {
writer.output(rec) }) } ) //where writer.ouput is a method that takes a
string and writer is an instance of a
