> 1. Create a table
> create table if not exists lineitem3(L_SHIPDATE string,L_SHIPMODE
> string,L_SHIPINSTRUCT string,L_RETURNFLAG string,L_RECEIPTDATE
> string,L_ORDERKEY string,L_PARTKEY string,L_SUPPKEY string,L_LINENUMBER
> int,L_QUANTITY double,L_EXTENDEDPRICE double,L_DISCOUNT double,L_TAX
> double,L_LINESTATUS string,L_COMMITDATE string,L_COMMENT string) STORED BY
> 'org.apache.carbondata.format' TBLPROPERTIES
> ('table_blocksize'='128','NO_INVERTED_INDEX'='L_SHIPDATE,L_SHIPMODE,L_SHIPINSTRUCT,L_RETURNFLAG,L_RECEIPTDATE,L_ORDERKEY,L_PARTKEY,L_SUPPKEY','sort_columns'='');
> 2. Run load queries and create pre-agg table queries in diff console:
> load data inpath "hdfs://hacluster/user/test/lineitem.tbl.1" into table
> lineitem3
> options('DELIMITER'='|','FILEHEADER'='L_ORDERKEY,L_PARTKEY,L_SUPPKEY,L_LINENUMBER,L_QUANTITY,L_EXTENDEDPRICE,L_DISCOUNT,L_TAX,L_RETURNFLAG,L_LINESTATUS,L_SHIPDATE,L_COMMITDATE,L_RECEIPTDATE,L_SHIPINSTRUCT,L_SHIPMODE,L_COMMENT');
> create datamap agr_lineitem3 ON TABLE lineitem3 USING
> "org.apache.carbondata.datamap.AggregateDataMapHandler" as select
> L_RETURNFLAG,L_LINESTATUS,sum(L_QUANTITY),sum(L_EXTENDEDPRICE) from lineitem3
> group by L_RETURNFLAG, L_LINESTATUS;
> 3. Check table content using aggregate query:
> select l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from
> lineitem3 group by l_returnflag, l_linestatus;
> 0: jdbc:hive2://10.18.98.34:23040> select
> l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from lineitem3
> group by l_returnflag, l_linestatus;
> +---------------+---------------+------------------+-----------------------+--+
> | l_returnflag | l_linestatus | sum(l_quantity) | sum(l_extendedprice) |
