> When cleaning the log, we attempt to write the cleaned messages using the
> message format configured for the topic, but as far as I can tell, we do not
> convert the wrapped messages in compressed message sets. For example, if
> there is an old compressed message set with magic=0 in the log and the topic
> is configured for magic=1, then after cleaning, the new message set will have
> a wrapper with magic=1, but the nested messages will still have magic=0. If
> this happens, there does not seem to be an easy way to recover without
> manually fixing up the log.
