Abstract:

Facing the scenarios of distributed storage and cross-domain circulation of data in various business domains in industrial scenarios, a cloud-edge collaborative data storage and retrieval architecture was proposed to address the problems of multiple and complex business systems, huge amounts of data, and the inability of some data to be uploaded to the cloud, aiming to achieve unified storage and efficient cross-domain circulation of large-scale data. In this architecture, a data encoding rule based on the RDF (Resource Description Framework) graph model and a multi-level efficient data storage strategy based on S-tree (Signature-tree) were designed to ensure that data that cannot be uploaded to the cloud are stored in the edge server, and data that can be uploaded to the cloud are stored in the cloud server. Besides, a cloud-edge collaborative storage-oriented index tree efficient collaborative retrieval method based on cloud-edge collaborative retrieval CECI-tree (Cloud-Edge Collaboration Index-tree) was proposed to improve efficiency of data retrieval effectively through the cloud-edge collaborative indexing mechanism. Experimental results of comparing the proposed architecture with methods such as RDF-3X and GRIN show that the proposed architecture performs better in terms of running efficiency and CPU utilization.

摘要:

面向工业场景各业务域中数据分布式存储和跨域流转的场景,针对业务系统多而复杂、数据量庞大且部分数据不可上云的问题,提出云边协同的数据存储与检索架构,旨在实现大规模数据的统一存储和跨域高效流转。该架构中,设计基于资源描述框架(RDF)图模型的数据编码规则和基于S-tree(Signature-tree)的数据多层级高效存储策略,从而保证不可上云数据存储在边缘侧服务器上,而可上云数据存储在云服务器上。此外,提出面向云边协同存储的基于云边协同索引树(CECI-tree)的高效协同检索方法,通过云边协同索引机制提高数据检索的效率。所提架构与RDF-3X和GRIN等方法进行比的实验结果表明,该架构的运行效率和CPU利用率表现更优。
