The data retrieval process in HBase is as follows:<\/p>\n

    \n
  1. The client sends a read request to the HBase cluster, which includes information such as table name, row key, and column family.<\/li>\n
  2. After receiving the request, HMaster determines the RegionServer where the data is located based on the table name and row key.<\/li>\n
  3. The RegionServer looks up the corresponding HFile based on the row key in the request and reads data from the HFile.<\/li>\n
  4. If the data is not in memory, it will be loaded from disk to memory and returned to the client.<\/li>\n
