-The Datagen connector allows for reading by data generation rules.
+Datagen 连接器允许按数据生成规则进行读取。
-The Datagen connector can work with [Computed Column syntax]({% link
dev/table/sql/create.zh.md %}#create-table).
-This allows you to generate records flexibly.
+Datagen 连接器可以使用[计算列语法]({% link dev/table/sql/create.zh.md %}#create-table)。
+这使您可以灵活地生成记录。
-The Datagen connector is built-in.
+Datagen 连接器是内置的。

-How to create a Datagen table
+怎么创建一个 Datagen 的表
----------------
-The boundedness of table: when the generation of field data in the table is
completed, the reading
-is finished. So the boundedness of the table depends on the boundedness of
fields.
+表的有界性：表中字段的数据生成完成后，就读取完成。 因此，表的有界性取决于字段的有界性。

表的有界性：当表中字段的数据全部生成完成后，source 就结束了。 因此，表的有界性取决于字段的有界性。
