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.
> Snappy compression isn't applied to messages written to disk on broker
> ----------------------------------------------------------------------
>
> 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.
