I would do one thing around _configOverriden. When user is changing tech config of any pool I would make a copy of the initial settings. You have all the means to make it simple - _poolConfig. Then within the setters whether it's a new value or previous (reverted) value you can compare initial config with the new one implementing Equals on the ConnectionPoolConfig. This way if only user reverts the changes to the pool, he will get rid of the false indication in the logs that something in the pool got changed.
