1、测试 travelrecord 表
travelrecord表，是根据ID主键的范围进行分片，分布在dn1,dn2,dn3三个节点，对应着conf/autopartition-long.txt文件
# range start-end ,data node index
# K=1000,M=10000.
0-500M=0
500M-1000M=1
1000M-1500M=2

4、测试 hotnews 表
hotnews表，基于主键取摸的方式分配到dn1,dn2,dn3上
create table hotnews(id int not null primary key ,title varchar(400) ,created_time datetime);
(product)[email protected] [TESTDB]> explain insert into hotnews(id,title,created_time) values(1,'first',now());
+-----------+--------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+--------------------------------------------------------------------+
| dn2 | insert into hotnews(id,title,created_time) values(1,'first',now()) |
+-----------+--------------------------------------------------------------------+
1 row in set (0.00 sec)
(product)[email protected] [TESTDB]> explain insert into hotnews(id,title,created_time) values(2,'two',now());
+-----------+------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+------------------------------------------------------------------+
| dn3 | insert into hotnews(id,title,created_time) values(2,'two',now()) |
+-----------+------------------------------------------------------------------+
1 row in set (0.00 sec)
(product)[email protected] [TESTDB]> explain insert into hotnews(id,title,created_time) values(3,'three',now());
+-----------+--------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+--------------------------------------------------------------------+
| dn1 | insert into hotnews(id,title,created_time) values(3,'three',now()) |
+-----------+--------------------------------------------------------------------+
1 row in set (0.00 sec)
insert into hotnews(id,title,created_time) values(1,'first',now());
insert into hotnews(id,title,created_time) values(2,'two',now());
insert into hotnews(id,title,created_time) values(3,'three',now());
insert into hotnews(id,title,created_time) values(5,'five',now());
(product)[email protected] [TESTDB]> select * from hotnews;
+----+-------+---------------------+
| id | title | created_time |
+----+-------+---------------------+
| 3 | three | 2016-02-23 14:34:19 |
| 2 | two | 2016-02-23 14:34:15 |
| 5 | five | 2016-02-23 14:34:22 |
| 1 | first | 2016-02-23 14:34:11 |
+----+-------+---------------------+
4 rows in set (0.00 sec)
- id为1，1%3=1，则到dn2上；
- id为2，2%3=2，则到dn3上；
- id为3，3%3=0，则到dn1上；
- id为5，5%3=2，则到dn3上，即对应dn3的index；
5、测试 employee 表
employee表，根据sharding-by-intfile （分片字段为sharding_id）规则进行分片，只在dn1,dn2存储数据，对应着conf/partition-hash-int.txt文件
10000=0
10010=1
create table employee (id int not null primary key,name varchar(100),sharding_id int not null);
insert into employee(id,name,sharding_id) values(1,'leader us',10000);
insert into employee(id,name,sharding_id) values(2,'me',10010);
insert into employee(id,name,sharding_id) values(3,'mycat',10000);
insert into employee(id,name,sharding_id) values(4,'mydog',10010);
(product)[email protected] [TESTDB]> select * from employee;
+----+-----------+-------------+
| id | name | sharding_id |
+----+-----------+-------------+
| 1 | leader us | 10000 |
| 3 | mycat | 10000 |
| 2 | me | 10010 |
| 4 | mydog | 10010 |
+----+-----------+-------------+
4 rows in set (0.00 sec)
6、测试 orders 表
customer表，根据sharding-by-intfile （分片字段为sharding_id）规则进行分片，只在dn1,dn2存储数据
orders表，ER分片，根据customer表的ID
首先创建customer表
create table customer(id int not null primary key,name varchar(100),company_id int not null,sharding_id int not null);
(product)[email protected] [TESTDB]> explain insert into customer (id,name,company_id,sharding_id)values(1,'wang',1,10000);
+-----------+-------------------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+-------------------------------------------------------------------------------+
| dn1 | insert into customer (id,name,company_id,sharding_id)values(1,'wang',1,10000) |
+-----------+-------------------------------------------------------------------------------+
1 row in set (0.00 sec)
(product)[email protected] [TESTDB]> explain insert into customer (id,name,company_id,sharding_id)values(2,'xue',2,10010);
+-----------+------------------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+------------------------------------------------------------------------------+
| dn2 | insert into customer (id,name,company_id,sharding_id)values(2,'xue',2,10010) |
+-----------+------------------------------------------------------------------------------+
1 row in set (0.00 sec)
(product)[email protected] [TESTDB]> explain insert into customer (id,name,company_id,sharding_id)values(3,'feng',3,10000);
+-----------+-------------------------------------------------------------------------------+
| DATA_NODE | SQL |
+-----------+-------------------------------------------------------------------------------+
| dn1 | insert into customer (id,name,company_id,sharding_id)values(3,'feng',3,10000) |
+-----------+-------------------------------------------------------------------------------+
1 row in set (0.00 sec)
insert into customer(id,name,company_id,sharding_id)values(1,'wang',1,10000);
insert into customer(id,name,company_id,sharding_id)values(2,'xue',2,10010);
insert into customer(id,name,company_id,sharding_id)values(3,'feng',3,10000);
insert into customer(id,name,company_id,sharding_id)values(4,'wo',4,10000);
(product)[email protected] [TESTDB]> select * from customer;
+----+------+------------+-------------+
| id | name | company_id | sharding_id |
+----+------+------------+-------------+
| 2 | xue | 2 | 10010 |
| 1 | wang | 1 | 10000 |
| 3 | feng | 3 | 10000 |
| 4 | wo | 4 | 10000 |
+----+------+------------+-------------+
4 rows in set (0.01 sec)
测试orders表
create table orders (id int not null primary key ,customer_id int not null,sataus int ,note varchar(100) );
//stored in db1 because customer table with id=3 stored in db1
insert into orders(id,customer_id) values(1,3);
//stored in db1 because customer table with id=1 stored in db1
insert into orders(id,customer_id) values(2,1);
//stored in db2 because customer table with id=2 stored in db2
insert into orders(id,customer_id) values(3,2);
(product)[email protected] [TESTDB]> select * from orders;
+----+-------------+--------+------+
| id | customer_id | sataus | note |
+----+-------------+--------+------+
| 1 | 3 | NULL | NULL |
| 2 | 1 | NULL | NULL |
| 3 | 2 | NULL | NULL |
+----+-------------+--------+------+
3 rows in set (0.00 sec)
(product)[email protected] [TESTDB]> select customer.name ,orders.* from customer ,orders where customer.id=orders.customer_id;
+------+----+-------------+--------+------+
| name | id | customer_id | sataus | note |
+------+----+-------------+--------+------+
| wang | 2 | 1 | NULL | NULL |
| feng | 1 | 3 | NULL | NULL |
| xue | 3 | 2 | NULL | NULL |
+------+----+-------------+--------+------+
3 rows in set (0.05 sec)
这里无法使用explain来查看insert执行分布，如果加上explain，直接被当成insert了；
