Abstract(in English) | Distributed Key-Value Stores are becoming applicable to various applications, such as not only Web applications but authentication systems. However, if the frequency of requests for each key varies greatly, this causes an uneven distribution of the load to the Key-Value Store servers. As a result, the number of servers required increases. To solve such a problem, we have studied a load balancing method which focuses on the frequency of requests for each key. However, since the method needs to change the load balancing algorithm, it is difficult to apply to existing Key-Value Store systems. Therefore, this paper presents a load balancing method which makes replicas of keys according to the frequency of each key. Since this method is transparent to a Key-Value Store system, it can be applied without changing the existing systems. An evaluation of the proposed method using simulation has confirmed that the system can successfully reduce the number of servers by 13% - 31%. |
