【摘要】：大規(guī)模評(píng)論數(shù)據(jù)的存儲(chǔ)與查詢性能對(duì)構(gòu)建于其上的各類應(yīng)用的快速響應(yīng)具有重要影響.同時(shí),異構(gòu)計(jì)算環(huán)境中各計(jì)算節(jié)點(diǎn)性能呈現(xiàn)差異,如何充分開(kāi)采各節(jié)點(diǎn)的計(jì)算和存儲(chǔ)性能,優(yōu)化大規(guī)模評(píng)論數(shù)據(jù)的存儲(chǔ)與查詢性能,是一個(gè)關(guān)鍵挑戰(zhàn).基于Redis集群的數(shù)據(jù)管理優(yōu)勢(shì),首先提出了一種同構(gòu)環(huán)境下基于卡槽存儲(chǔ)平衡的大規(guī)模評(píng)論數(shù)據(jù)存儲(chǔ)模型;然后論證了卡槽數(shù)目與節(jié)點(diǎn)查詢效率的關(guān)系,以"負(fù)載與訪問(wèn)性能相平衡"的原則分配卡槽,進(jìn)一步設(shè)計(jì)了異構(gòu)環(huán)境下的集群節(jié)點(diǎn)負(fù)載計(jì)算和存儲(chǔ)分配方法,充分開(kāi)采了異構(gòu)Redis集群中不同節(jié)點(diǎn)的性能.實(shí)驗(yàn)結(jié)果表明,提出的存儲(chǔ)模型具有很好的存儲(chǔ)平衡效果,提升了集群的整體查詢效率.
[Abstract]:The storage and query performance of large-scale comment data has an important impact on the rapid response of various applications built on it. At the same time, the performance of computing nodes in heterogeneous computing environments is different. How to fully exploit the computing and storage performance of each node and optimize the storage and query performance of large-scale comment data is a key challenge. Firstly, a large scale review data storage model based on slot storage balance in isomorphic environment is proposed. Then, the relationship between the number of card slots and the efficiency of node query is demonstrated. According to the principle of "balance between load and access performance", the load calculation and storage allocation method of cluster nodes in heterogeneous environment is further designed. The performance of different nodes in heterogeneous Redis cluster is fully exploited. Experimental results show that the proposed storage model has a good storage balance effect and improves the overall query efficiency of the cluster.
