> Specifies the table store distribution policy. Data is assigned to each bucket according to the hash value of bucket-key.
>  * It is primary key when table has primary key. The user can specify a bucket key, it should be part of primary keys.
>  * It is all fields when table has no primary key.
> If there are filter conditions for specific fields, reasonable settings can give a big performance boost to the table, but care needs to be taken to avoid data skewing.
