An index pushdown uses the pushed-down keys to perform index lookups on a foreign key index of the fact table.
索引下推使用下推键执行事实表外键索引的查询。 ibm
In a bit- vector pushdown, for each push-down, the database server hashes the keys from the dimension table to create a bit vector, which is shipped to the fact table.
在位向量下推中，对于每次下推，数据库服务器通过散列维度表中的键来创建发送至事实表的位向量。 ibm
In the latter case, you needed to implement the pushdown process in the CMP method.
后来，需要在 CMP方法中实现叠加过程。 ibm
The pushed-down join keys can be used in an index pushdown or a bit- vector push- down.
下推连接键可用于索引下推或位向量下推。 ibm
While its current scope is very modest, IBM hopes to enhance the tuning utility in future releases to more accurately characterize the capabilities of and improve pushdown to ODBC sources.
目前，这个调优实用程序的适用范围还不够大， IBM希望在将来的版本中进一步增强该实用程序，以便更精确地描述 ODBC数据源的能力，并使更多的操作可以下推到 ODBC数据源。 ibm
Before access path selection, the DB2 optimizer transforms SQL statements into forms that are semantically identical, such as by using predicate pushdown or predicate transitive closure.
在选择访问路径之前， DB2优化器将 SQL语句转换成语意上一致的形式，例如使用谓词下推或谓词传递闭包。 ibm
Changing certain nickname attributes can improve performance by influencing which operations can be considered for pushdown.

If your federated system needs to access a data source with the ODBC wrapper, you might want to consider checking the server option PUSHDOWN.
如果您的联邦系统需要用 ODBC包装器访问一个数据源，那么您可能需要考虑检查服务器选项 PUSHDOWN。 ibm
Improved pushdown of predicate evaluation, joins, and grouping operations results in reduced data movement between CF and Federation Server, which usually improves performance.
通过改进谓词计算、连接和分组操作的下推，可以减少 CF与 Federation Server之间的数据移动，这通常可以提高性能。 ibm
