Ewen Cheslack-Postava commented on KAFKA-4005:
----------------------------------------------
I agree this would be useful, but moving out of the target versions since we
haven't had any sort of PR for a couple of versions -- let's move it back in to
a target version when we have a real solution.
> Add per topic compression ratio in broker and consumer.

> Currently we only have compression ratio metric on the producer side. It
> would be very useful to have that in the brokers and consumers for each topic
> as well.
> On the broker side, the compression ratio can be potentially depending on the
> produce request or the final message written to the disk. It is probably more
> useful to use the compression ratio of the messages we finally writes to
> disk. If the messages are compressed in different compression type, we can
> maintain the compression ratio for each type separately.
> The consumer side compression ratio would be for each topic and compression
> type combination as well.
