Ismael Juma resolved KAFKA-746.
-------------------------------
    Resolution: Fixed

I am going to mark this as fixed as there have been no reports of this for several years.

>                 Key: KAFKA-746
>                 URL: https://issues.apache.org/jira/browse/KAFKA-746
>             Project: Kafka
>          Issue Type: Bug
>          Components: producer 
>    Affects Versions: 0.7.2
>            Reporter: Esko Suomi
>            Assignee: Jun Rao
>            Priority: Minor
>
> We recently tested 0.7.2 performance using different compression codecs for messages and noticed that when using Snappy (compression.codec = 2 in Producer configuration) the messages written to topic partitions were written without compression. Compared to GZIP (compression.codec = 1) this is especially peculiar since with GZIP the partition files themselves were compressed as expected.
> I did walk through the 0.8 code briefly and didn't spot any obvious reasons why this would be happening so I'm now handing this issue completely into your able hands.
