【摘要】：隨著信息技術(shù)的發(fā)展,越來越多的人參與到社交網(wǎng)絡(luò)當(dāng)中,社交網(wǎng)絡(luò)儼然已經(jīng)成為了人們開拓人脈、維護(hù)好友關(guān)系、娛樂和業(yè)務(wù)拓展的一種主要方式。面對社交網(wǎng)絡(luò)的龐大用戶群體、用戶間復(fù)雜的好友關(guān)系以及海量的信息處理,社交網(wǎng)絡(luò)的好友消息推送已經(jīng)成為了限制社交網(wǎng)絡(luò)規(guī)模的主要問題。目前社交網(wǎng)絡(luò)好友消息推送模式主要有三種：推模式、拉模式以及推拉模式,無論采用哪一種方式都會帶來大量的IO操作給系統(tǒng)帶來性能上的瓶頸,面對社交網(wǎng)絡(luò)好友消息數(shù)據(jù)的一次寫多次讀的特點(diǎn)和搜索引擎查詢快速的特性,本文提出了一種利用分布式搜索引擎替換數(shù)據(jù)庫實(shí)現(xiàn)社交網(wǎng)絡(luò)平臺的好友消息推送的設(shè)計(jì)思想。利用搜索引擎內(nèi)存搜索的特點(diǎn),減少用戶查詢所帶來10操作。利用分布式計(jì)算的特性,擴(kuò)展系統(tǒng)的規(guī)模。本論文就以下幾方面進(jìn)行了研究。(1)分析目前主流的社交網(wǎng)絡(luò)平臺的推送模式,提出了利用搜索引擎替換數(shù)據(jù)庫實(shí)現(xiàn)消息中間件以達(dá)到社交網(wǎng)絡(luò)平臺消息推送的目的。(2)分析目前開源的分布式搜索引擎產(chǎn)品,針對社交網(wǎng)絡(luò)好友推送的需求,設(shè)計(jì)一條基于歸并排序的分布式搜索引擎(Distributed Search Engine Using Merge, DSM),針對分布式系統(tǒng)的特性進(jìn)行設(shè)計(jì),保證系統(tǒng)的穩(wěn)定性和可擴(kuò)展性。(3)以搜索引擎實(shí)現(xiàn)好友消息推送為基礎(chǔ),設(shè)計(jì)一套基于服務(wù)的社交網(wǎng)絡(luò)系統(tǒng),解決系統(tǒng)模塊間調(diào)用、異步處理等大型網(wǎng)絡(luò)設(shè)計(jì)問題,最終利用該社交網(wǎng)絡(luò)系統(tǒng)發(fā)布消息,測試消息推送功能。
[Abstract]:With the development of information technology, more and more people participate in social networks. Social networks have become people to open up their networks and maintain good friends. A major form of entertainment and business expansion. In the face of the huge user base of social networks, the complex relationships between users and the vast amount of information processing, Friend messaging on social networks has become a major problem limiting the size of social networks. At present, there are three main types of push mode: push mode, pull mode, and push pull mode, and push pull mode, push pull mode, push pull mode, push pull mode, push pull mode, push pull mode, and push pull mode. Either way, it will bring a lot of IO operations to the system performance bottleneck, in the face of the social network friend message data write multiple times read characteristics and search engine query fast characteristics, In this paper, a design idea of using distributed search engine to replace database to realize friend message push on social network platform is put forward, and the characteristics of search engine memory search are used. Using the characteristics of distributed computing to expand the scale of the system. This paper analyzes the push mode of the mainstream social network platform in the following aspects. This paper proposes using search engine to replace database to realize message middleware in order to achieve the purpose of message push on social network platform. (2) analyzing the open source distributed search engine product, aiming at the demand of friend push on social network. A distributed Search Engine Using merge (DSM) based on merging and sorting is designed to ensure the stability and extensibility of the distributed system. A set of social network system based on service is designed to solve the problems of large network design such as calling between system modules, asynchronous processing and so on. Finally, the social network system is used to publish messages and test the function of message push.
