+# be 配置项说明
+## enable load strict 配置说明
+
+be 的配置中有一个参数 enable_load_strict 用于限制所有导入方式中类型转换如果遇到错误数据，是否严格 filter。
+
+enable load strict 参数只对导入中的类型转换有效，对于类型转换来说，如果 enable_load_strict 为true，则错误的数据将被filter。
+
+对于导入的某列包含函数变换的，导入的值和函数的结果一致，strict 对其不产生影响。（其中 strftime 等 broker 系统支持的函数也属于这类）。
+
+### strict 与类型转换关系
+
+这里以列类型为 int 来举例
+注：当表中的列允许导入空值时
+
+source data | source data example | string to int   | enable_load_strict | load_data
+------------|---------------------|-----------------|--------------------|---------
+空值        | \N                  | N/A             | true or false      | NULL
+not null    | aaa                 | NULL            | true               | filtered
+not null    | aaa                 | NULL            | false              | NULL
+not null    | 1                   | 1               | true or false      | correct data
