This allows starting and stopping separately each protocol server without restarting ClickHouse. This also allows adding or removing `listen_host` entries, which start and stops servers for all enabled ports. When stopping a server, the listening socket is immediately closed (and available for another server). Protocols with persistent connections try to wait for any currently running query to finish before closing the connection, but idle connection are closed quickly (depending on how often the protocol is polled). An extra ProfileEvent is added, `MainConfigLoads`, it is incremented every time the configuration is reloaded. This helps when trying to assess whether the new configuration was applied. |
