我正在查看https://mariadb.com/kb/en/mariadb/using-connect-partitioning-and-sharding/
中的以下示例create table partemp (
id int NOT NULL,
first_name varchar(16) NOT NULL,
last_name varchar(30) NOT NULL,
birth date NOT NULL date_format='DD/MM/YYYY',
hired date NOT NULL date_format='DD/MM/YYYY',
job char(16) NOT NULL,
salary double(10,2) NOT NULL,
city char(12) default 'boston' special=PARTID,
index XID(id)
) engine=CONNECT table_type=FIX file_name='E:/Data/Test/%s.txt';
alter table partemp
partition by list columns(city) (
partition `atlanta` values in('atlanta'),
partition `boston` values in('boston'),
partition `chicago` values in('chicago'));
我只是想知道,为了在关系数据库中基本上模拟类似PARQUET的存储格式,可以将这样的内容扩展到多个列吗?
