This paper proposes a method for improving the efficiency of synchronization between relational databases (RDBs) and graph databases (GDBs) to realize digital twins in an All-Photonics Network (APN). Because RDBs place a heavy processing load on the extraction of relationships between data, the current approach for digital twins is to use a GDB that is synchronized data from the existing RDB. Furthermore, while it is essential to design graphs suitable for each specific application, there is a challenge in that synchronizing data from graphs that are not used or are used infrequently leads to excessive consumption of computational resources. Therefore, we focus on access patterns for each function and the relationships between functions to propose a method for dynamically controlling synchronization on/off. Specifically, we combine (1) synchronization control based on the activation and deactivation of functions, (2) suspension of synchronization when there is no access for a certain period of time, and (3) control of synchronization resumption based on the degree of correlation between functions. Evaluation results confirmed that the proposed method suppresses unnecessary synchronization and decreases synchronization processing time.
