https://issues.apache.org/jira/browse/CARBONDATA-910] carbondata implement partition feature, it's very useful. But if we want add partition data in carbondata table,we must be use {{ alter}} syntax as following:
> {code}
> carbon.sql("ALTER TABLE temp.test_table ADD PARTITION('2017-10-18', '2017-10-19')")
> {code}
> If you have many partitions that should be add to some table, you should run the sql many times, It's boring and inefficiency. So it;s very useful to support static and partition dynamic in insert into/overwrite DML:
> {code}
> Static partition:
> INSERT OVERWRITE TABLE tablename1 [PARTITION (partcol1=val1) [IF NOT EXISTS]] select_statement1 FROM from_statement;
> INSERT INTO TABLE tablename1 [PARTITION (partcol1=val1)] select_statement1 FROM from_statement;
> Dynamic partition:
> INSERT OVERWRITE TABLE tablename1 [PARTITION (partcol1) [IF NOT EXISTS]] select_statement1 FROM from_statement;
> INSERT INTO TABLE tablename1 [PARTITION (partcol1)] select_statement1 FROM from_statement;
> {code}
