1·An index push-down has the following advantages.

索引下推包含以下优点。

2·Step 2.4: Look for other push-down opportunities.

步骤2.4：寻找其他下推机会。

3·Star join plan utilizes push-down hash join technology.

星型连接计划利用下推散列连接技术。

4·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。

5·The push-down decision is made by the wrapper during the planning phase, while working with the query optimizer.

下推的决定是包装器在计划阶段与查询优化器一起做出的。

6·The primary purpose of a push-down hash join is to reduce number of rows processed from the fact table, which probes each of the hash tables.

下推散列连接的主要目的是减少处理的事实表行数，这样可以探测每个散列表。

7·Listings 7 and 8 show a sample CIM-XML message exchange — request and response — with the CIMOM (over HTTP) in the push-down method through the CIM Adapter.

清单7和8展示了一个CIM - XML消息交换的范例——通过CIM适配器使用叠加方法中的CIMOM(基于HTTP)来进行请求和响应。

8·A star join plan utilizing push-down hash join technology makes hash joins more effective primarily due to reduction of fact table (probe table) rows early on.

利用下推连接技术的星型连接计划使得散列连接更加有效的主要原因是，在初期减少了事实表(探测表)的行数。

9·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。

10·The government had done everything it could to push down inflation.

政府已经竭尽全力遏制通货膨胀。《柯林斯英汉双解大词典》

4·Inspect the optimized SQL in the db2exfmt or Visual Explain output, as this is the basis for the planning decision of the relational data source push-down analysis and the query optimizer.

检查db 2 exfmt或Visual Explain输出中经过优化的SQL，因为这是关系数据源下推分析和查询优化器确定计划的基础。
