HBase Physical Storage

All lines in 1.Table are arranged in the dictionary order of the Rowkey.

2.Table split into multiple hregion in the direction of the row

　　

3.Region is split by size. Each table starts with only one region, and as the data is inserted into the table, region grows, and when it increases to a threshold, hregion is divided into two hregion. When the rows in the table are increasing, There will be more and more region.

The 4.HRegion is the smallest unit of distributed storage and load balancing in HBase. The minimum unit refers to different hregion that can be distributed across different hregionserver, but the same hregion cannot be distributed on different servers.

5.Hregion is the smallest unit of distributed storage, but it is not the smallest unit stored. In fact, HBase consists of one or more stores, each store a columnfamily, Each store is made up of a memstore and 0 to multiple storefile.

: StoreFile will be saved on hdfs| in the form of hfile
