-----------------------------------
Summary: Add per topic compression ratio in broker and consumer.
Key: KAFKA-4005
URL: https://issues.apache.org/jira/browse/KAFKA-4005
Project: Kafka
Issue Type: Improvement
Components: clients, core
Reporter: Jiangjie Qin
Fix For: 0.10.1.0
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.
