Now proxysql throws error immediately when active connections reached the configured value. Any support available in proxysql to queue the connections ?

Exception received - User ‘\*\*\*\*\*\*’ has exceeded the ‘max\_user\_connections’ resource (current value: \*)  
As the incoming request rate / user is not known clearly, I would like to provide reasonable value but at the same time I need to handle the request little later if max\_user\_connection has exceeded.

Thanks ahead!

ProxySQL will not queue connections that fail to establish to backend servers. Either increase max\_connections in MySQL, or implement better logic in your application.
