Is this the proper form to report Python driver bugs? I have one oddball server where connections to the Cassandra database frequently timeout without specifying a connection-timeout.
While trying to connect to the Cassandra database (version 3.11.10) using the python 3.25.0 driver I encountered the following issue:
I can connect to the DB using the following code snippet:
self.cluster = Cluster(execution_profiles={EXEC_PROFILE_DEFAULT: self.profile},
control_connection_timeout=180, connect_timeout=180)
self.session = self.cluster.connect('foo')
I cannot connect to the DB using the following code snippet:
self.cluster = Cluster(execution_profiles={EXEC_PROFILE_DEFAULT: self.profile})
self.cluster.connect_timeout = 180
self.cluster.control_connection_timeout = 180
self.session = self.cluster.connect('foo')
When using the defective code above the following exception is returned within 5 seconds, the driver is not honoring the cluster.connect_timeout and/or the control_connection_timeout settings when they are made outside of the Custer()'s constructor.
