Public Member Functions
shared_ptr< DuckDB >	GetInstance (const string &database, const DBConfig &config_dict)
	Gets a DB Instance from the cache if already exists (Fails if the configurations do not match)

shared_ptr< DuckDB >	CreateInstance (const string &database, DBConfig &config_dict, bool cache_instance=true, const std::function< void(DuckDB &)> &on_create=nullptr)
	Creates and caches a new DB Instance (Fails if a cached instance already exists)

shared_ptr< DuckDB >	GetOrCreateInstance (const string &database, DBConfig &config_dict, bool cache_instance, const std::function< void(DuckDB &)> &on_create=nullptr)
	Either returns an existing entry, or creates and caches a new DB Instance.

shared_ptr< DuckDB >	GetOrCreateInstance (const string &database, DBConfig &config_dict, CacheBehavior cache_behavior=CacheBehavior::AUTOMATIC, const std::function< void(DuckDB &)> &on_create=nullptr)
