In PySpark you can use forEachPartition and call Kinesis or any external API for that partition, or you can also use map and call out to Kinesis per record.

#push to kinesis using boto3 APIs
rdd.foreachPartition(pushToKinesis())

#push to kinesis using boto3 APIs
rdd.map(lambda l: pushToKinesis(l))
