This article mainly introduces "hbase table structure and installation and deployment process". In daily operation, I believe many people have doubts about hbase table structure and installation and deployment process. The editor consulted all kinds of information and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "hbase table structure and installation and deployment process". Next, please follow the editor to study!

Hbase table structure and installation and deployment

You only need to specify the table name and column family when creating a table

Each row is a record, the number of fields in each row is arbitrary, and each field should be specified for storage.

Field name and field value. When querying a field, you need to specify the coordinates: table name-row key-column family

Field name clolumn family field
