首先在逻辑上将表与其自身连接，然后将更具有选择性的非起始索引键作为索引绑定过滤器，应用于起始键值的每个惟一的组合。
The table is logically joined to itself, and the more selective non-leading index keys are applied as index bound filters to each unique combination of the leading key values.
与此类似，如果两张表通过一个外键连接起来，我们也称其为连接的。
Similarly if two tables are connected via a foreign key, they are connected.
这些连接将进一步扩展到指示板，为需要索引的键提供显示的数据。
Further wires radiate from there to the dashboard, providing the keys they need to index the data they display.
这种分子是由一群化学键连接而成的原子。
A molecule is a group of atoms held together by chemical bonds.
性能的提高取决于连接键被下推时所在维度表的过滤选择度。
The performance improvement depends on the selectivity of the filter on the dimension table from which the join keys are pushed down.
并列而排的转移rna阅读邻近的密码子，带来氨基酸并将其以共价键连接起来。
Juxtaposed tRNAs, reading adjacent codes, bring together amino acids, which are then covalently joined to together.
构建散列表时，连接键被下推用于过滤事实表的行，性能也显著提高。
When hash tables are built, join keys are pushed down and used to filter the rows of the fact table, and performance improves dramatically.
下推连接键可用于索引下推或位向量下推。
The pushed-down join keys can be used in an index pushdown or a bit-vector push-down.
星型连接计划中，数据库服务器在维度表中构建散列表的同时从维度表中下推键来过滤事实表。
In a star join plan, the database server pushes down keys from a dimension table to filter the fact table at the same time as it builds the hash table on the dimension table.
模式不需要明确指定一列是主键或唯一键来产生星型连接计划。
The schema does not need to specify explicitly that a column is a primary or unique key to produce a star join plan.
通过对上述两个表的连接键(pdb_id)进行散列处理来分布两个表也能确保给定pdbml文档中所有原子行均能作为本身的PDBML文档存储在相同的数据库分区中。
Distributing both tables by hashing on their join key (pdb_id) also ensures that all atom rows for a given PDBML document are stored in the same database partition as the PDBML document itself.
如果在连接谓词中使用分区键（partitioning key），最后还有一点考虑需要顾及。
When you use the partitioning key in the join predicate, a final consideration needs to be mentioned.
