使用内存连接器对查询测试或临时存储非常有用。例如，在使用鸢尾花数据集时，可以
将它当作一个外部数据源的简单替代品来配置，参见
1.4.7

项目包含许多连接器，但有时你会遇到这样的情况：需要为一

好消息是，这通常不会有太大阻碍。
Trino
团队和社区正在不断扩大可用连接器的列表，
所以当你读到本书时，这个列表可能已经变得更长了。
连接器也可以从

连接器也可以从数据库系统的供应商那里获得，因此，询问想查询的系统的所有者或创

最后，你必须记住，
Trino
是一个围绕开源项目的开放社区。因此，我们鼓励你去查看现
有连接器的代码，并根据需要创建新的连接器。理想情况下，你甚至可以参与

中其他用户和贡献者的帮助，并将该连接器用于其他场景，这样就可以提升该连接器的 ...
