5.1. system¶
system connector提供了了集群的运行指标及相关的源元数据信息，这些集群信息、运行状况信息也可以通过sql的方式进行查询。system connect不需要专门配置 catalog，由presto集群在启动的时候进行自动添加。
system connector主要包含information_schema、jdbc、metadata、runtime四个schema。information_schema主要包含本catalog下的信息，jdbc包含整个presto 集群的服务信息，metadata包含整个presto集群的元数据信息，runtime包含presto集群的运行状况信息。

5.1.1. information_schema¶
information_schema提供了presto catalog的元数据信息，默认情况下每个presto catalog都会存在一个information_schema。information_schema包含catalog下的 schema信息、function信息、catalog下的所有表信息、catalog下的视图信息、表权限信息、表的列字段信息。
presto:system> show tables from system.information_schema;

5.1.1.1. columns¶
columns可以查看该catalog下的所有字段信息。show columns就是查看该表下的数据，只是添加了过滤条件。
