Primary Data Types

Query performance can be improved by leveraging like data types (i.e. INT32 to INT32) when joining foreign keys in a fact table to primary keys in a dimension table.

通过在将 fact 表中的外键与 dimension 表中的主键进行连接时采用 like 数据类型（例如 INT32 to INT32），可提高查询性能。

The most basic parser functionality doesn't support a wide array of data types; therefore, irregular or unusual data, which is common, is a primary source of difficulty.

最基本的解析器功能支持的数据类型不多，因此处理不规则或少见的数据(经常会遇到这种情况)成为最主要的困难。
