commit b38f72b2129ee377cb80132ca9c0794b60585be6 Author: Takashi Kajinami <[email protected]> Date: Wed Feb 7 01:46:47 2024 +0900 Completely disable rpc workers when rpc_workers=0 Currently at least 1 rpc worker is launched even when a user requests zero workers by setting rpc_workers=0. The setting of rpc_workers=0 is used when ml2-ovn plugin is used without any additional agent, and in this deployment pattern the single rpc worker is not at all used. This change ensures no rpc worker is launched when rpc_workers options is explicitly set to 0. This may be classified as a breaking change, but is consistent with the earlier change[1] for rpc_workers=0.

From neutron-server log, rpc_workers and rpc_state_report_workers are set to 0. 2024-02-05 13:05:33.159 70458 DEBUG neutron.common.config [-] rpc_state_report_workers = 0 log_opt_values /usr/lib/python3.9/site-packages/oslo_config/cfg.py:2602 2024-02-05 13:05:33.159 70458 DEBUG neutron.common.config [-] rpc_workers = 0 log_opt_values /usr/lib/python3.9/site-packages/oslo_config/cfg.py:2602 ps shows there is one rpc worker running. neutron 70458 1 70458 0.3 1.8 133664 144496 /usr/bin/python3 -s /usr/bin/neutron-server ... neutron 70499 70458 70499 11.4 3.1 246792 248240 neutron-server: api worker (...) neutron 70500 70458 70500 11.0 3.1 243640 249488 neutron-server: api worker (...) neutron 70502 70458 70502 0.3 1.7 141196 142132 neutron-server: rpc worker (...) neutron 70503 70458 70503 0.3 1.8 145256 146356 neutron-server: MaintenanceWorker (...) neutron 70504 70458 70504 0.0 1.7 135472 135604 neutron-server: periodic worker (...)
