Minor Description
I created a table using :
CREATE TABLE uniqdata_dict_sort(CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES('DICTIONARY_INCLUDE'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1', 'SORT_SCOPE'='GLOBAL_SORT');
When I executed the following query:
desc formatted uniqdata_dict_sort
It shows the following output:
0: jdbc:hive2://localhost:10000> desc formatted uniqdata_dict_sort;
