| 10. | First , we improved the stem mechanism , which was used to deal with multi - joins in the eddy . we proposed a method that can keep the intermediate results of the join operator , without reducing any adaptivity of the original stem mechanism . and so more compute resources are saved to improve the whole throughput of the system
一是对用于在eddy中自适应地处理多路join操作的stem机制作出了重大的改进，提出按需探测的中间结果算法，实现了在保持原有的stem算法的适应性的基础上，对中间结果进行适当的保留，从而在join的匹配率较高的情况下，减少了重复计算，提高了系统吞吐率，同时也对原有的路由策略也进行了针对stem机制的有益的改进。 |
