-For 0.8, we have correlation id so we can potentially interleave requests/responses
-
-There are a few levels of abstraction:
-
-* Protocol support: encode/decode the requests/responses
-* Socket support: send/recieve messages
-* API support: higher level APIs such as: get_topic_metadata
-
-
-# Methods of producing
-
-* Round robbin (each message to the next partition)
-* All-to-one (each message to one partition)
-* All-to-all? (each message to every partition)
-* Partitioned (run each message through a partitioning function)
-** HashPartitioned
-** FunctionPartition
-
-# Possible API
-
-    client = KafkaClient("localhost:9092")
-
-    producer = KafkaProducer(client, "topic")
-    producer.send_string("hello")
-
-    consumer = KafkaConsumer(client, "group", "topic")
-    consumer.seek(10, 2) # seek to beginning (lowest offset)
-    consumer.commit() # commit it
-    for msg in consumer.iter_messages():
-        print msg
