Hi folks,

Im trying to see if there is a feature within mysql/percona/mariadb in general that does this kind of feature to reject queries when a service is overloaded. Similar to back pressure system.

TIA

Hi @elisia,  
When MySQL reaches max connections, it will simply error out saying that max connections has been reached. There are no queuing capabilities built-in.
