HBase區(qū)域

區(qū)域是表格可用性和分布的基本元素，它由每個列族（Column Family）的存儲（Store）組成。對象的層次結(jié)構(gòu)如下所示：

Table                    (HBase table)
    Region               (Regions for the table)
        Store            (Store per ColumnFamily for each Region for the table)
            MemStore     (MemStore for each Store for each Region for the table)
            StoreFile    (StoreFiles for each Store for each Region for the table)
                Block    (Blocks within a StoreFile within a Store for each Region for the table)
