hive分区表

分区表创建

row format delimited fields terminated by ',';指明以逗号作为分隔符

依靠插入表创建分区表  从表sample_table选择 满足分区条件的 列插入到分区表中

insert into table partition_table partition(gender='M') select id,name from sample_table where gender='M';
insert into table partition_table partition(gender='F') select id,name from sample_table where gender='F';

explain可以查看执行计划

$ explain select *from sample_table where gender = 'M';

$ explain select *from partition_table where gender = 'M';
