mysql - 在 Mysql 上连接 100GB 表

Question

我有 2 个包含 100GB 数据的表。

第一个表

+-------------+---------------+
| id          | code          |
+-------------+---------------+
| 10255911    |sample data    |
| 10255912    |sample data    |
| 10255913    |sample data    |
+-------------+---------------+

第二个表

+-------------+---------------+
| id          | code2         |
+-------------+---------------+
| 10255911    |sample data    |
| 10255912    |sample data    |
| 10255913    |sample data    |
+-------------+---------------+

我需要最快且最佳的方式来连接表以创建 View 。使用 UNION ALL 函数非常慢。表(VIEW)应该是

+-------------+---------------+-------------+
| id          | code          | code2       |
+-------------+---------------+-------------+
| 10255911    |sample data    |sample data  |
| 10255912    |sample data    |sample data  |
| 10255913    |sample data    |sample data  |
+-------------+---------------+-------------+

Answer 1

在两个表的 ID 列上创建索引。

SELECT table_1.id
    , table_1.code 
    , table_2.code2
FROM table_1 INNER JOIN table_2
  ON table_1.id = table_2.id
  ;
