摘要
为解决海量教学数据的高效处理和管理,提出基于HBase/Spark的教学大数据存储及索引模型设计.先基于组合行键构建HBase表,根据教学Course分类进行预分区,并构建cost评分函数,来检测并迁移负载,达到解决数据存储时写热点和负载均衡的问题.语义解析、组合行键索引查询、Spark并行属性条件过滤实现教学大数据高效查询.实验证明基于HBase/Spark的教学大数据的模型,能够实现更加高效的教学大数据访存管理.
In order to solve the efficient processing and management problems of massive teaching data,this paper proposes the design of a big-data storage and index model for teaching based on HBase/Spark.First,HBase table is constructed based on the combined row keys,pre-divided according to the teaching course-classification,and a cost-scoring function is constructed to detect and migrate the load so as to solve the problems of writing hot spots and load balancing in data storage.Semantic parsing,the combined row key index query and the Spark parallel attribute condition filter help realize the efficient query of big data for teaching.The experiment proves that this model can realize more efficient retrieval management of the big data for teaching.
