clear_reloadable_connections!
clear_reloadable_connections!()
public
Clears the cache which maps classes and re-connects connections that require reloading.
The pool first tries to gain ownership of all connections. If unable to do so within a timeout interval (default duration is spec.db_config.checkout_timeout * 2 seconds), then the pool forcefully clears the cache and reloads connections without any regard for other connection owning threads.
