Monasca bumped confluent-kafka-python to newer version.
And that generates side effects on AArch64 (all distributions Kolla supports) and on Ubuntu 22.04 (any architecture).
Why?
#error "confluent-kafka-python requires librdkafka v1.9.0 or later. Install the latest version of librdkafka from the Confluent repositories, see http://docs.confluent.io/current/installation.html"
Debian/stable has 1.6.0, Ubuntu/22.04 has 1.8.0 versions.
On x86-64 architecture we can fetch wheel files for CentOS Stream 8, CentOS Stream 9, Debian/stable and Ubuntu/20.04 as they use Python 3.6/3.8/3.9 versions for which there are wheel files provided by upstream.
On Ubuntu 22.04 we have Python 3.10 for which there is no wheel file from upstream...
Sure, on x86-64 we can use extra repository from upstream and build 'confluent-kafka-python' from source. And probably we will go that way later in a cycle.
But on AArch64 we have no other way than disabling build of Monasca. There is no way to satisfy dependency :(
