Customized sharding options Customized sharding options can build a relationship with the sharding items, converting the sharding items’numbers represents Shanghai and 2 represents Guangzhou. Customized sharding options make the codes more readable, if we have customized options 0=Beijing,1=Shanghai,2=Guangzhou, we can simply use Beijing, Shanghai
