algorithm则代表了执行分片函数的名字。 function标签,name代表分片算法的名字,算法的名字要和上面的tableRule中的<algorithm>标签相对应。class:指定分片算法实现类。此处需要填写为“numberrange”或者“com.actiontech.dble.route.function.AutoPartitionByLong"的分区规则,property指定了对应分片算法的参数。不同的算法参数...
在项目中例如现在有user表,存在 id、name、age、addr、gender、interest;在项目中 name,age、addr会被频繁的调用,而gender、interest频率低,当数据量达到百万甚至千万级别时,为了提高查询效率,将常用的字段与非常用字段进行分离,这时候就可以考虑将name、age、addr与gender、interest分别用两张表A、B来存储,这样就将原...

function标签,name代表分片算法的名字,算法的名字要和上面的tableRule中的<algorithm>标签相对应。class:指定分片算法实现类。此处需要填写为“patternrange”或者“com.actiontech.dble.route.function.PartitionByPattern"的分区规则,property指定了对应分片算法的参数。不同的算法参数不同。
It is easier to use range coordinates when you have code that iterates through a set of cells in a loop, or when the range coordinates are calculated dynamically as part of the algorithm. A range specification must contain a sheet name; Excel Web Services does not recognize the "cu...
