Currently Kafka driver for an oslo.messaging uses kafka-python==0.9.5 and mostly broken. This package version supports only low level Kafka producer and consumer API which are marked as deprecated now [1]. Using of these interfaces bring a big concern to the message processing, because current KafkaConsumer has not any consuming coordination. This fact causes a message duplication for the several consumers of one topic. This behavior is specific to Ceilometer and services which read and process notifications from other services. New version of kafka-python allows to use async thread safe message producers and coordinated consumers [1]. [1] http://kafka-python.readthedocs.io/en/master/changelog.html#feb-15-2016 The driver is currently experimental, python-kafka<1.0.0 API have major issue described above that can't make the oslo.messaging driver works, so we prefer having a working driver with a non-synced dependencies, that the reverse.
