 ### Key 分区
 
-TiDB 从 v7.0.0 开始支持 Key 分区。在 v7.0.0 之前的版本中，创建 Key 分区表时，TiDB 会将其创建为非分区表并给出告警。 
+TiDB 从 v7.0.0 开始支持 Key 分区。在 v7.0.0 之前的版本中，创建 Key 分区表时，TiDB 会将其创建为非分区表并给出告警。
 
 Key 分区与 Hash 分区都可以保证将数据均匀地分散到一定数量的分区里面，区别是 Hash 分区只能根据一个指定的整数表达式或字段进行分区，而 Key 分区可以根据字段列表进行分区，且 Key 分区的分区字段不局限于整数类型。TiDB Key 分区表的 Hash 算法与 MySQL 不一样，因此表的数据分布也不一样。
