| ## Should I use TiSpark or TiDB server for a query? | ||

| It is recommended to use TiDB server if you query single table collection or you use the filtering query, because TiDB server shows better performance on the columnar storage. It is recommended to use TiSpark if you query table joins. |

@ilovesoup Please confirm whether "It is recommended to use TiDB server if you query single table collection or you use the filtering query, because TiDB server shows better performance on the columnar storage. It is recommended to use TiSpark if you query table joins." means the same thing with "如果查询以单表集合和过滤为主，那么 TiDB server 比 TiSpark 在列存上拥有更好的性能；如果查询以表连接为主，那么推荐使用 TiSpark。" Thanks a lot!

It is recommended to use TiDB server if you query single table with filtering and aggregation, because TiDB server shows better performance on the columnar storage. It is recommended to use TiSpark if you query table joins.

Here I made a mistake in Chinese version: "以单表集合和过滤" -> "以单表聚合和过滤"
