There is a serious regression bug in Pulsar C++ client 3.1.0 [1], on which the Python client is based. And the Python client 3.0.0 also introduces a deadlock problem [2]. In addition, now the Python client supports Python 3.11.
I'll start a 3.1.0 release for Pulsar Python client. [1] https://lists.apache.org/thread/81dwlq1vb21pq1jt83okqln8oyc3c2wj [2] https://github.com/apache/pulsar-client-python/pull/87 Thanks, Yunze
