【摘要】 信息系统支撑的业务量非常大的情况下,从数据量及查询要求来看首选HBase。HBase是一个分布式、面向列的数据库,适合存储非结构化数据,在现今大数据时代得到了广泛的应用。基于此,介绍HBase数据库中行键的主要特点,以Warehose数据表为例,分析行键如何设计,考虑到HBase的负载均衡现象,分析可能出现的热点问题并提出通过加盐、Hash散列、反转三种方式进行防治。更多还原

【Abstract】 In the case of the huge amount of business supported by information system, HBase is preferred in terms of data volume and query requirements. HBase is a distributed, column-oriented database, suitable for storing unstructured data, which has been widely used in the era of big data. Based on this, the main characteristics of row keys in HBase database are introduced. Taking Warehose data table as an example, how to design row keys is analyzed. Considering the load balancing phenomenon of HBase, the hot issues that may arise are analyzed, and the prevention and cure methods are put forward by adding salt, Hash hash and inversion.更多还原
