什么是 CSR 索引作为连接优化技术?
What is CSR indexing as a join optimization technique?
Spark Graphx 论文在以下上下文中提到了 CSR 索引:
GraphX recasts system optimizations developed in the context of graph
processing systems as join optimizations (e.g., CSR indexing, join
elimination, and join-site specification) and materialized view
maintenance (e.g., vertex mirroring and delta updates)
然而当我用谷歌搜索
CSR indexing join optimization
结果与
相关
Corporate Social Responsibility.
现在我确定我们都支持 ;) 但是,我对更多与技术相关的首字母缩略词和语义的信息感兴趣。
好的,我在矩阵运算论文里面找到了它:它是
Compressed Sparse Row
详情:
CSR permits indexed access to rows. Similar to COO, CSR storage
structure also consists of three sparse vectors, non-zero vector,
column vector and row vector. Index structure differs in the formation
of row vector. In CSR row vector consists of pointers to each row of
the matrix.
