MyBUD自适应分布式存储管理的设计与实现

面对日益增长的非结构化数据管理需求,实现了基于"自由表"数据模型和BUD(bank of unstructured data)参考体系模型的非结构化数据管理平台MyBUD系统。提出了一种能够根据非结构化数据的类型和访问特点自适应地选择分布式存储子系统的方法,同时也对MyBUD进行了TPCC测试和非结构化数据存取实验。结果表明,这种自适应的数据存储方法为MyBUD系统提供了高效的可扩展存储层,为采用数据库方法实现对结构化和非结构化数据统一管理的进一步研究工作奠定了基础。

Design and Implementation of Adaptive Storage Management System in MyBUD

Facing with the ever-growing demand for managing unstructured data,this paper proposes a free-table data model and a reference framework BUD(bank of unstructured data),and further implements a prototype platform MyBUD based on the free-table and BUD.It also proposes a novel method to adaptively select a storage sub-system in MyBUD,which manipulates the specific type of unstructured data more efficiently according to its features.In experiment,the paper sets up a TPCC benchmark and a large volume of unstructured video data to evaluate its performance while managing different co-existing categories of data.The experimental results show that the proposed algorithm provides efficient storage service and establishes foundation for further research on unified management of structured and unstructured data in the database approach.
