HBase中Region,Store,StoreFile,ColumnFamily的关系

 

The HRegionServer opens the region and creates a corresponding HRegion object. When

the HRegion is opened it sets up a Store instance for each HColumnFamily for every table

as defined by the user beforehand. Each Store instance can, in turn, have one or more

StoreFile instances, which are lightweight wrappers around the actual storage file

called HFile. A Store also has a MemStore, and the HRegionServer a shared HLog in-stance。
