[opt](mtmv) Materialized view partition track supports date_trunc and…
… optimize the fail reason (apache#35562) this depends on apache#34781 1. Materialized view partition track supports date_trunc and optimize the fail reason. 2. it supports create partition mv as following: this mv will be partition updated by day CREATE MATERIALIZED VIEW mv_6 BUILD IMMEDIATE REFRESH AUTO ON MANUAL partition by(date_trunc(date_alias, 'day')) DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS SELECT date_trunc(t1.L_SHIPDATE, 'hour') as date_alias, t2.O_ORDERDATE, t1.L_QUANTITY, t2.O_ORDERSTATUS, count(distinct case when t1.L_SUPPKEY > 0 then t2.O_ORDERSTATUS else null end) as cnt_1 from (select * from lineitem where L_SHIPDATE in ('2017-01-30')) t1 left join (select * from orders where O_ORDERDATE in ('2017-01-30')) t2 on t1.L_ORDERKEY = t2.O_ORDERKEY group by t1.L_SHIPDATE, t2.O_ORDERDATE, t1.L_QUANTITY, t2.O_ORDERSTATUS;
