kafka-python v1.4.5 drastically impacts consumer performance.

[jutley]

I made an issue over in the kafka-python project about new versions causing the consumer to perform with only an eighth of the throughput. You can see the here:
dpkp/kafka-python#1888

In our case, this is a big issue as the the latest versions of this project can no longer keep up with our __consumer_offsets topic in some clusters.

I think that this project should explicitly depend on kafka-python v1.4.4 until this is fixed.

Decided in #31 not to hold back kafka-python for now, since the performance decrease in 1.4.5+ isn't expected to be problematic for most users.

Leaving this issue open until dpkp/kafka-python#1888 is resolved.

If you're affected by this issue, please weigh in!

@braedon kafka-python 1.4.7 should be in a good state. Can we cut a new release of this project to update the dependency?

[braedon]

I've released 0.5.4 with exclusions for kafka-python 1.4.5 and 1.4.6. The 0.5.4 docker tag has been built using kafka-python 1.4.7.
