用户表涉及的实体
改进1:第三范式:将依赖传递的列分离出来
比如:登录名<-用户级别<-级别积分上限,级别积分下限
改进2:尽量做到冷热数据的分离,减小表的宽度
用户登录表(customer_login)
CREATE TABLE customer_login(
customer_id INT UNSIGNED AUTO_INCREMENT NOT NULL COMMENT '用户ID',

分区表特点:逻辑上为一个表,在物理上存储在多个文件中
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY HASH(customer_id) PARTITIONS 4;
区别就在于加了 PARTITION
这个命令。
文件结构上的区别
customer_login_log.frm
customer_login_log.ibd
customer_login_log.frm
customer_login_log#P#p0.ibd
customer_login_log#P#p1.ibd
customer_login_log#P#p2.ibd
customer_login_log#P#p3.ibd
按HASH分区的特点
UNIX_TIMESTAMP(login_time)
特点:
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY RANGE (customer_id) (
PARTITION p0 VALUES LESS THAN (10000),
PARTITION p1 VALUES LESS THAN (10000),
PARTITION p2 VALUES LESS THAN (10000),
PARTITION p3 VALUES LESS THAN MAXVALUE
);
Range分区的适用范围
特点:
CREATE TABLE customer_login_log(
login_id INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '登陆日志ID',
customer_id INT UNSIGNED NOT NULL COMMENT '登陆用户ID',
login_time TIMESTAMP NOT NULL COMMENT '用户登陆时间',
login_ip INT UNSIGNED NOT NULL COMMENT '登陆IP',
login_type TINYINT NOT NULL COMMENT '登陆类型:0未成功,1成功',
PRIMARY KEY pk_loginid(login_id)
) ENGINE = innodb COMMENT '用户登陆日志表'
PARTITION BY LIST (login_type) (
PARTITION p0 VALUES (1,3,5,7,9),
PARTITION p1 VALUES (2,4,6,8)
);
业务场景:
解决:
如何查看分区是否正确:
information_schema.PARTITIONS
ALTER TABLE customer_login_log ADD PARTITION (PARTITION p4 VALUES LESS THAN(2018))
ALTER TABLE customer_login_log DROP PARTITION p0;

ALTER TABLE customer_login_log EXCHANGE PARTITION p1 WITH TABLE arch_customer_login_log
ALTER TABLE customer_login_log DROP PARTITION p2

为以后数据库迁移提供方便
避免跨库操作,把经常一起关联查询的表放到一个DB中
为方便识别表所在的DB,在表名前增加库名前缀
用户数据库(mc_customerdb)
商品数据库(mc_productdb)
订单数据库(mc_orderdb)
