Detailed Description

Connections pool, allows to handle multiple connections for specific connection string.

Note connections_manager provide more generic interface and hides pools inside it. So you generally should use this class only when you prefer to avoid using some global singleton object.

Unlike connections_manager, it uses pool by default unless its size defined as 0.

All this class member functions are thread safe to use from several threads for the same object
