taojintianxia opened a new issue #5219: redundant insert (insert twice) URL: https://github.com/apache/incubator-shardingsphere/issues/5219 ## Question hi , there today I got an wired behavier, I insert a data as following sql through sharding proxy, however , there are two records insert into database ``` INSERT INTO `t_order`(`id`,`user_id`) VALUES(5,105); ```  followings are my `config-sharding.yaml` : ```yaml shardingRule: tables: t_order: actualDataNodes: ds_${0..1}.t_order_${0..1} databaseStrategy: inline: shardingColumn: user_id algorithmExpression: ds_${user_id % 2} tableStrategy: inline: shardingColumn: order_id algorithmExpression: t_order_${order_id % 2} keyGenerator: type: SNOWFLAKE column: id ``` and this is the structure of t_order : ```sql CREATE TABLE `t_order` ( `id` int(11) NOT NULL, `user_id` varchar(12) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ``` I'm not sure why , I checked manual, but seems the config is not incorrect.
