Storage structure of hbase

Each table in Hbase is divided into multiple child tables (HRegion) according to a certain range through row keys (rowkey). By default, if a HRegion exceeds 256m, it will be divided into two, which is managed by HRegionServer and which HRegion is allocated by Hmaster. When HRegion accesses a child table, it creates a HRegion object and then creates an store instance for each Column Family of the table. Each store has 0 or more StoreFile corresponding to it, and each StoreFile corresponds to an HFile,HFile that is the actual storage file. Therefore, a HRegion also has an instance of MemStore.
