| 摘 要： | 在非关系数据库下的动态负载均衡算法中引入查询成本指标,通过分析历史查询日志来估计查询代价,并应用到负载均衡中的负载决策部分,使得负载排序更准确.同时对当前任务的查询代价进行估计,以找到合适的接受此任务的节点,从而使负载均衡变被动为主动,有效地缩短平均查询响应时间,提升系统的整体性能.

| Abstract: | This paper is based on the non-relational database of load balancing algorithm by introducing the query cost index. The load is more accurate through the analysis of the historical inquires the log to estimate inquires the price, and applied to the decision-making part of the load in the load balancing. At the same time figure out query cost of the current task to find the right to accept the task node, thus the load balancing change from passive to active, effectively shortening the average query response time, and improve the overall performance of the system. |
