1) data skew
数据倾斜
1.
Taking the characteristic of the variant-length of vector data records into account,HCSDP algorithm divides uniformly the huge volume of spatial data set into multiple parts and putting them onto the different processing nodes for avoiding the data skew.
在充分考虑空间信息的海量特征以及矢量数据存储记录的不定长等特点的前提下,该算法可实现并行空间数据库中海量空间数据记录在多个存储设备上的均衡划分,以避免出现数据倾斜现象,从而提高了空间数据的检索与查询效率。
