In Doris, data is logically described in the form of tables. A table consists
of rows and columns. Row is a row of user data. Column is used to describe
different fields in a row of data.
-Columns can be divided into two categories: Key and Value. From a business
perspective, Key and Value correspond to dimension columns and indicator
columns, respectively.
+Columns can be divided into two categories: Key and Value. From a business
perspective, Key and Value correspond to dimension columns and indicator

table creation statement. The column after the keyword 'unique key' or
'aggregate key' or 'duplicate key' in the table creation statement is the key
column, and the rest except the key column is the value column .
