Mycat本地模式的自增长分表操作

Mycat对表t_rc_rule_monitor做分表操作

在mysql上执行(没有t_rc_rule_monitor)

DROP TABLE IF EXISTS t_rc_rule_monitor;
CREATE TABLE t_rc_rule_monitor(
  id int(20) NULL auto_increment ,
  system_id varchar(32) NOT NULL,
  group_no varchar(32) NOT NULL ,
  rule_code varchar(30) NOT NULL ,
  merchant_id varchar(20) NOT NULL,
  payclass_id int(20) NOT NULL,
  is_risk char(1) NOT NULL ,
  cost_time int(5) NULL ,
  create_date LONG NULL ,
primary key(id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;


配置:
vi server.xml
<property name="sequnceHandlerType">0</property>

vi schema.xml
<table name="T_RC_RULE_MONITOR" primaryKey="ID" autoIncrement="true" dataNode="dn1,dn2" rule="mod-long"/>

vi sequence_conf.properties

GLOBAL.HISIDS=
GLOBAL.MINID=10001
GLOBAL.MAXID=200000000
GLOBAL.CURID=10000

T_RC_RULE_MONITOR.HISIDS=
T_RC_RULE_MONITOR.MINID=10001
T_RC_RULE_MONITOR.MAXID=200000000
T_RC_RULE_MONITOR.CURID=10000

vi rule.xml

<function name="mod-long" class="io.mycat.route.function.PartitionByMod">
  <!-- how many data nodes -->
  <property name="count">2</property>
</function>

向该表插入数据不用写id字段,会自行插入增长id

例子:

  insert into tt(id,name_) values(next value for MYCATSEQ_GLOBAL,1);

  insert into tt(id,name_) values(next value for MYCATSEQ_TT,2);

   insert into tt(name_) values(5);
