(English Abstract)
With an increase in the utilization of graph streams in various applications, a continuous subgraph matching scheme is required to search the subgraphs that undergo changes in real time. In this paper, we propose an efficient continuous subgraph matching scheme that reuses indexing and performs distributed processing in graph stream environments. In order to perform distributed processing, we propose a query decomposition method based on the degree and subsequently manage the decomposed subqueries as an index. The proposed scheme reuses indexing information to reduce the load on the index caused by the environment in which multiple queries are entered. We also conduct query allocation through a cost model that calculates the indexing load of each server. For efficient performance of distributed processing in stream environments, the proposed scheme was implemented in Storm. Various performance evaluations were conducted to demonstrate the superiority of the proposed scheme.
