Access plan directives that force the optimizer to use the designated access method for data retrieval, either sequential scan or index scan.
访问计划指示，强制优化器使用指定的访问方法进行数据检索，要么是连续扫描，要么是索引扫描。
If the inner table does not have an index, the database server will compare the cost of building an index on the table to the cost of a sequential scan, and will choose the one with the least cost.
如果内部表没有索引，那么数据库服务器就会将在表上构建索引的成本与连续扫描的成本进行比较，然后选择成本最低的那一种方法。
During the foreign key enforcement, the server USES the sequential scan, instead of foreign key index.
在外键加强过程中，服务器使用顺序扫描，而不是外键索引。
Although index entries are sequential, there is no guarantee that rows with adjacent index entries will reside on the same data pages.
虽然索引项是连续的，但是不保证包含相邻索引项的行将驻留在同一数据页上。
It is easier to describe this in detail using the explain output shown in Listing 7. Sequential scan is done on the source table, and index look-up is done on the target table.
可以很方便地利用清单7中展示的explain输出来描述其细节，可以对源表进行顺序扫描，并且在目标表上完成索引查找。
Therefore a randomized index column can relieve contention problems for sets of similar or sequential values, but it's no help with identical values.
因此，随机化的列可以减轻一组相似值或序列值的争用问题，但对于相同的值没有帮助。
