             Summary: Log cleaner should write compacted messages using 
configured compression type
                 Key: KAFKA-2213
                 URL: https://issues.apache.org/jira/browse/KAFKA-2213
             Project: Kafka
          Issue Type: Bug
            Reporter: Joel Koshy


In KAFKA-1374 the log cleaner was improved to handle compressed messages. There 
were a couple of follow-ups from that:
* We write compacted messages using the original compression type in the 
compressed message-set. We should instead append all retained messages with the 
configured broker compression type of the topic.
* While compressing messages we should ideally do some batching before 
compression.
* Investigate the use of the client compressor. (See the discussion in the RBs 
for KAFKA-1374)
