Joel Koshy commented on KAFKA-1499:
-----------------------------------

That sounds reasonable. Another option would be to allow the config to be in 
LogConfig and "split" ConfigNames into LogConfigNames and TopicConfigNames. 
Although broker.compression.enable is not a valid topic-level config it is a 
reasonable log-level config. TopicConfigNames can be used for validating topic 
configs. What do you think? [~jkreps] do you have any preference?

> A given topic can have messages in mixed compression codecs. i.e., it can
> also have a mix of uncompressed/compressed messages.
> It will be useful to support a broker-side configuration to recompress
> messages to a specific compression codec. i.e., all messages (for all
> topics) on the broker will be compressed to this codec. We could have
> per-topic overrides as well.
