Block Nested-Loop JoinAlgorithm(块嵌套循环连接算法) Block Nested-loop(BNL)连接算法利用缓存外部循环读取的数据行来减少在内表中读取的次数。e.g.假如外表读取并缓存10行数据,缓存传递给以下个内表,内表可以在缓存中直接比较这10行数据,而不用再重新读取外表的10行数据,以数量级的方式减少内表读取次数。 MYSQL...

Block Nested-Loop and Batched Key Access Joins Batched Key Access (BKA) Join算法通过index和join buffer访问joined表,BKA算法支持inner join,outer join 和semi join操作,包括嵌套的outer join,BKA的好处包括提高join性能(由于更有效率的table scan),同时,前文的Block Nested loop(BNL)join 算法被扩展也支持这...

Simulation and validation results using a Hardware in the Loop (HIL) prototype under different operation conditions are presented in order to validate the proposed converter topology and control strategy. Keywords: multilevel converter; quasi-nested converter; reduced switching devices topology; dc-link ...

The vertical profiles (Figure 14 and Figure 15) for salinity, temperature, and horizontal velocity were examined in the South Port Everglades. In the case of salinity, the 3-D plot displayed a similar pattern along the water depth profile, except for the beginning of May, when freshwater ...
