Prasanna Ravichandran updated CARBONDATA-2731:
----------------------------------------------
Description:
While creation of the timeseries datamap, queries to which it would apply would
also be defined. SO when the user uses that same query after creation of TS
datamap, then that query should fetch the data from the TS datamap created.
Test queries:
create table brinjal (imei string,AMSize string,channelsId string,ActiveCountry
string, Activecity string,gamePointId double,deviceInformationId
double,productionDate Timestamp,deliveryDate timestamp,deliverycharge double)
STORED BY 'org.apache.carbondata.format' TBLPROPERTIES('table_blocksize'='1');
LOAD DATA INPATH 'hdfs://hacluster/user/prasanna/vardhandaterestruct.csv' INTO
TABLE brinjal OPTIONS('DELIMITER'=',', 'QUOTECHAR'=
'"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'=
'imei,deviceInformationId,AMSize,channelsId,ActiveCountry,Activecity,gamePointId,productionDate,deliveryDate,deliverycharge');
CREATE DATAMAP agg0_time ON TABLE brinjal USING 'timeSeries' DMPROPERTIES
('EVENT_TIME'='productionDate','SECOND_GRANULARITY'='1') AS SELECT
productionDate, SUM(imei) FROM brinjal GROUP BY productionDate;
explain SELECT productionDate, SUM(imei) FROM brinjal GROUP BY productionDate;
