1、測(cè)試 travelrecord 表

<!-- auto sharding by id (long) -->
<table name="travelrecord" dataNode="dn1,dn2,dn3" rule="auto-sharding-long" />

travelrecord表，是根據(jù)ID主鍵的范圍進(jìn)行分片，分布在dn1,dn2,dn3三個(gè)節(jié)點(diǎn)，對(duì)應(yīng)著conf/autopartition-long.txt文件

     with any table whose sharding node is in the same data node -->
<table name="company" primaryKey="ID" type="global" dataNode="dn1,dn2,dn3" />

company表，定義為全局表，在dn1,dn2,dn3 三個(gè)節(jié)點(diǎn)都有相同的記錄

<table name="goods" primaryKey="ID" type="global" dataNode="dn1,dn2" />

goods表，定義為全局表，在dn1,dn2兩個(gè)節(jié)點(diǎn)都有相同的記錄

create table goods(id int not null primary key,name varchar(200),good_type tinyint,good_img_url  varchar(200),good_created date,good_desc varchar(500), price double);

(product)test@10.1.1.167 [TESTDB]> explain insert into goods(id,name,good_type,good_img_url,good_created,good_desc,price) values(1,'hp',1,'http://a.jgp',now(),'惠普',100.00);

4、測(cè)試 hotnews 表

<!-- random sharding using mod sharind rule -->
<table name="hotnews" primaryKey="ID" dataNode="dn1,dn2,dn3" rule="mod-long" />

hotnews表，基于主鍵取摸的方式分配到dn1,dn2,dn3上

create table hotnews(id int  not null primary key ,title varchar(400) ,created_time datetime);

(product)test@10.1.1.167 [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()) |

+-----------+------------------------------------------------------------------+
| DATA_NODE | SQL                                                              |

| dn3       | insert into hotnews(id,title,created_time) values(2,'two',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)test@10.1.1.167 [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為1，1%3=1，則到dn2上；
  • id為2，2%3=2，則到dn3上；
  • id為3，3%3=0，則到dn1上；
  • id為5，5%3=2，則到dn3上，即對(duì)應(yīng)dn3的index；

5、測(cè)試 employee 表

<table name="employee" primaryKey="ID" dataNode="dn1,dn2" rule="sharding-by-intfile" />

employee表，根據(jù)sharding-by-intfile （分片字段為sharding_id）規(guī)則進(jìn)行分片，只在dn1,dn2存儲(chǔ)數(shù)據(jù)，對(duì)應(yīng)著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)test@10.1.1.167 [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、測(cè)試 orders 表

<table name="customer" primaryKey="ID" dataNode="dn1,dn2" rule="sharding-by-intfile">
    <childTable name="orders" primaryKey="ID" joinKey="customer_id" parentKey="id">
    <childTable name="order_items" joinKey="order_id" parentKey="id" />
    </childTable>
    <childTable name="customer_addr" primaryKey="ID" joinKey="customer_id" parentKey="id" />
</table>

customer表，根據(jù)sharding-by-intfile （分片字段為sharding_id）規(guī)則進(jìn)行分片，只在dn1,dn2存儲(chǔ)數(shù)據(jù)
orders表，ER分片，根據(jù)customer表的ID

首先創(chuàng)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)test@10.1.1.167 [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)test@10.1.1.167 [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)test@10.1.1.167 [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)test@10.1.1.167 [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)

測(cè)試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)test@10.1.1.167 [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)test@10.1.1.167 [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)

這里無(wú)法使用explain來(lái)查看insert執(zhí)行分布，如果加上explain，直接被當(dāng)成insert了；
